Description

Storage device and data processing method TECHNICAL FIELD

[0001] The disclosed embodiments of the present application relate to the technical field of flash memory, and more particularly, to a storage device and a data processing method. BACKGROUND

[0002] When writing data, a NAND product issues data from a host to a NAND device, and the NAND device caches the data from the host into a master buffer register (SRAM buffer). When the data reaches a certain amount, the NAND device issues the relevant data to the NAND for writing, and clears the data in the master buffer register. Due to process reasons, some blocks (Block) in the NAND may have program status fail (PSF) or uncorrectable error correction code (UECC). However, many consumer-level masters (DRAM-Less) immediately clear the data from the host after issuing the data to the NAND. At this time, due to the occurrence of PSF or UECC, the data is not completely written into the NAND, resulting in loss of the data from the host.

[0024] In order for those skilled in the art to better understand the technical solutions of the present application, the technical solutions of the present application will be further described in detail below in combination with the drawings and specific embodiments.

[0025] Please refer to FIG. 1, which is a structural schematic diagram of a storage device according to an embodiment of the present application. The storage device 10 is connected with a host device 20. Specifically, the storage device 10 comprises at least one storage block 110 and a controller 120, wherein the controller 120 is connected with each of the at least one storage block 110 and is connected with the host device 20.

[0026] The controller 120 is configured to perform a read data operation from any one of the at least one storage block 110 in response to a read instruction received from the host device 20. In response to receiving a read instruction sent from the host device 20, the controller 120 performs a read data operation from any one of the at least one storage block 110.

[0027] The controller 120 is configured to determine the storage block as a first type storage block in response to the instruction error correction value of the data in the storage block satisfying a preset condition when performing the read data operation from the storage block, wherein the first type storage block is used for a first operation set. For example, the preset condition is that the instruction error correction value of the data in the storage block is less than a preset instruction error correction value X, and the instruction error correction value of the data in the storage block satisfies the preset condition when performing the read data operation from the storage block, i.e. the instruction error correction value of the data in the storage block is less than X when performing the read data operation from the storage block, then the storage block is determined as a first type storage block, for example, as a class A Block. The first type storage block can be understood as a normal operation block, which is used for the first operation set. The first operation set includes data processing operations interacting with the host device 20, etc.

[0028] The controller 120 is configured to determine the storage block as a second type storage block in response to the instruction error correction value of the data in the storage block not satisfying a preset condition, wherein the second type storage block is used for a second operation set, for example, the preset condition is that the instruction error correction value of the data in the storage block is less than a preset instruction error correction value X, and the instruction error correction value of the data in the storage block does not satisfy the preset condition when a read data operation is performed on the storage block, that is, the instruction error correction value of the data in the storage block is greater than or equal to X when the read data operation is performed on the storage block, and the storage block is determined as the second type storage block, for example, a B type Block. The second type storage block can be understood as a potential risk bad block, and is only used for the second operation set. Understandably, if the existence of the potential risk bad block cannot be determined, PSF or UECC may occur, causing data not to be completely written into the NAND, which may result in Host data loss.

[0029] In the embodiment, the storage device 10 is connected with the host device 20. Specifically, the storage device 10 includes at least one storage block 110 and a controller 120, wherein the controller 120 is connected with each of the at least one storage block 110 and is connected with the host device 20. The controller 120 is configured to determine the storage block as a first type storage block in response to the instruction error correction value of the data in the storage block satisfying a preset condition when a read data operation is performed on the storage block, and determine the storage block as a second type storage block in response to the instruction error correction value of the data in the storage block not satisfying the preset condition, wherein the first type storage block is used for a first operation set, and the second type storage block is used for a second operation set, that is, different types of storage blocks correspond to different operation sets. That is, by effectively identifying the potential risk block in the NAND, the risk of product data loss is reduced, and the data reliability of the NAND product is improved.

[0030] In some embodiments, the first operation set includes a write data operation with the host device 20.

[0031] The controller 120 is configured to determine the storage block as a first type storage block in response to the instruction error correction value of the data in the storage block satisfying a preset condition when a read data operation is performed on the storage block, and determine the storage block as a second type storage block in response to the instruction error correction value of the data in the storage block not satisfying the preset condition, wherein the first type storage block is used for a first operation set, and the second type storage block is used for a second operation set, wherein the first operation set includes a write data operation with the host device 20, for example, the first operation set includes a data processing operation related to the host device 20, such as a write data operation, an operation corresponding to a related firmware algorithm, and the like, that is, the first type storage block participates in performing a write data operation, a related operation corresponding to a firmware algorithm, and the like.

[0032] In some embodiments, the second operation set includes a data refresh operation and / or a data garbage collection operation.

[0033] The controller 120 is further configured to determine the storage block as a second type storage block in response to the instruction error correction value of the data in the storage block not satisfying a preset condition when performing a read data operation from the storage block, for example, the preset condition is that the instruction error correction value of the data in the storage block is less than a preset instruction error correction value, the preset instruction error correction value is X, if the instruction error correction value of the data in the storage block B2 is greater than or equal to X when performing a read data operation from the storage block B1, the storage block B1 is determined as a second type storage block, the second type storage block is only used for a second operation set, wherein the second operation set includes a data refresh operation (refresh) and / or a data garbage collection operation (Garbage Collection, GC), that is, the second type storage block participates in performing the data refresh operation and / or the data garbage collection operation, for example, the storage block B1 only participates in performing the data refresh operation and / or the data garbage collection operation.

[0034] It can be understood that the second operation set and the first operation set can be completely different or partially different. Specifically, the second operation set and the first operation set can be completely different, that is, the first operation set includes a write data operation, for example, a write data operation, an operation corresponding to a related firmware algorithm, etc. with the host device 20, but does not include a data refresh operation and / or a data garbage collection operation, and the second operation set only includes the data refresh operation and / or the data garbage collection operation, that is, the second operation set does not include the write data operation, for example, the second operation set does not include a data processing operation related to the interaction with the host device 20, that is, the second type storage block does not participate in performing the write data operation, the operation corresponding to the related firmware algorithm, etc., so that the second operation set is completely different from the first operation set; or the second operation set and the first operation set can be partially different, that is, the first operation set includes a write data operation, for example, a write data operation, an operation corresponding to a related firmware algorithm, etc. with the host device 20, and also includes a data refresh operation and / or a data garbage collection operation, and the second operation set only includes the data refresh operation and / or the data garbage collection operation, that is, the second operation set does not include the write data operation, for example, the second operation set does not include a data processing operation related to the interaction with the host device 20, that is, the second type storage block does not participate in performing the write data operation, the operation corresponding to the related firmware algorithm, etc., so that the second operation set is partially different from the first operation set, that is, the first operation set can include the second operation set.

[0035] For example, in response to the instruction error correction value of the data in the storage block A1 satisfying the preset condition when a read data operation is performed from the storage block A1, the storage block A1 is determined as a first type storage block, and then the storage block A1 is used for a first operation set, and the first operation set includes a write data operation of the host device 20; in response to the instruction error correction value of the data in the storage block B1 not satisfying the preset condition, the storage block B1 is determined as a second type storage block, and then the storage block B1 is used for a second operation set, and the second operation set does not include the write data operation of the host device 20, that is, the second type storage block does not participate in the execution of the write data operation, the operation corresponding to the related firmware algorithm, and the like, thereby reducing the risk of data loss caused by programming failure when the Host data is written.

[0036] In some embodiments, the controller 120 is further configured to perform, in response to the storage block being determined as the first type storage block, a write data operation of the host device 20 on the storage block, and perform, in response to the storage block being determined as the second type storage block, a data refresh operation and / or a data garbage collection operation on the storage block.

[0037] In response to the instruction error correction value of the data in the storage block satisfying the preset condition when a read data operation is performed from the storage block, the storage block is determined as a first type storage block, and in response to the storage block being determined as the first type storage block, a write data operation of the host device 20 is performed on the storage block, for example, in response to the instruction error correction value of the data in the storage block A1 being less than a preset instruction error correction value X when a read data operation is performed from the storage block A1, the storage block A1 is determined as a first type storage block, and then a write data operation of the host device 20 can be performed on the storage block A1; in response to the instruction error correction value of the data in the storage block not satisfying the preset condition when a read data operation is performed from the storage block, the storage block is determined as a second type storage block, and in response to the storage block being determined as the second type storage block, a data refresh operation and / or a data garbage collection operation is performed on the storage block, for example, in response to the instruction error correction value of the data in the storage block B1 being greater than or equal to the preset instruction error correction value X when a read data operation is performed from the storage block B1, the storage block B1 is determined as a second type storage block, and then a data refresh operation and / or a data garbage collection operation can be performed on the storage block B1.

[0038] In some embodiments, the controller 120 is further configured to perform, in response to the storage block being determined as the first type storage block, a write data operation of the host device 20 on the storage block, and perform, in response to the storage block being determined as the second type storage block, a data refresh operation and / or a data garbage collection operation on the storage block.

[0039] For example, when the instruction correction value of the data in the storage block B1 is greater than or equal to the preset instruction correction value X during the read data operation from the storage block B1, the storage block B1 is determined as the second type of storage block, the data refresh operation and / or the data garbage collection operation can be performed on the storage block B1, after the data refresh operation and / or the data garbage collection operation is completed, the data verification operation is performed on the storage block, and in response to the data verification passing, the storage block is released, for example, after the data refresh operation and / or the data garbage collection operation is performed on the storage block B1, the data verification operation is performed on the storage block B1, and in response to the data verification passing, the storage block B1 is released, that is, the space of the data source storage block B1 is released after the data is written correctly.

[0040] In some embodiments, the controller 120 is further configured to, in response to the data being written correctly in the storage block during the write data operation on the storage block, performing other operations in the first operation set on the storage block, and in response to the data being written incorrectly in the storage block during the write data operation on the storage block, marking the storage block as an unusable storage block.

[0041] For example, when the instruction correction value of the data in the storage block A1 is less than the preset instruction correction value X during the read data operation from the storage block A1, the storage block A1 is determined as the first type of storage block, the write data operation with the host device 20 is performed on the storage block A1, in response to the data being written correctly in the storage block during the write data operation on the storage block, performing other operations in the first operation set on the storage block, that is, in response to the data being written correctly in the storage block A1 during the write data operation on the storage block A1, performing other operations in the first operation set on the storage block A1, such as related operations corresponding to the firmware algorithm, etc.; in response to the data being written incorrectly in the storage block during the write data operation on the storage block, marking the storage block as an unusable storage block, that is, in response to the data being written incorrectly in the storage block A1 during the write data operation on the storage block A1, marking the storage block A1 as an unusable storage block, and the storage block A1 no longer participates in the execution of the data processing operation related to the interaction with the host device 20.

[0042] In some embodiments, the write data operation with the host device 20 includes: receiving a write instruction from the host device 20, and in response to the write instruction, performing the write data operation on the storage block.

[0043] The controller 120 is configured to determine the storage block as a first type storage block in response to the instruction error correction value of the data in the storage block satisfying a preset condition when performing the read data operation on the storage block, and determine the storage block as a second type storage block in response to the instruction error correction value of the data in the storage block not satisfying the preset condition, the first type storage block is used for a first operation set, and the second type storage block is used for a second operation set, wherein the first operation set includes a write data operation of the host device 20, for example, the first operation set includes a data processing operation related to the host device 20, and the second operation set does not include the write data operation of the host device 20, wherein the write data operation of the host device 20 includes receiving a write instruction from the host device 20, and performing the write data operation on the storage block in response to the write instruction, for example, when performing the read data operation on the storage block A1, the instruction error correction value of the data in the storage block A1 is less than a preset instruction error correction value X, and the storage block A1 is determined as the first type storage block, and the write data operation is performed on the storage block A1 in response to receiving the write instruction from the host device 20.

[0049] In response to the instruction error correction value of the data in the storage block satisfying a preset condition when a read data operation is performed on the storage block, the storage block is determined as a first type storage block, wherein the first type storage block is used for a first operation set, for example, the preset condition is that the instruction error correction value of the data in the storage block is less than a preset instruction error correction value X, and when the read data operation is performed on the storage block, the instruction error correction value of the data in the storage block satisfies the preset condition, i.e., the instruction error correction value of the data in the storage block is less than X, the storage block is determined as the first type storage block, for example, as a class A Block, and the first type storage block can be understood as a normal operation block, which is used for the first operation set, and the first operation set includes a data processing operation interacting with the host device 20.

[0053] In some possible implementations, the method can be implemented by a processor invoking computer readable instructions stored in a memory, as shown in FIG. 3, the method can include the following steps:

[0054] S31: The host device issues a read instruction to the storage device, so that the storage device performs the above-mentioned data processing method.

[0055] The host device 20 issues a read instruction to the storage device 10, so that the storage device 10 performs the above-mentioned data processing method. Specifically, the storage device 10 performs a read data operation from any one of the at least one storage block 110 in response to the read instruction received from the host device 20; determines the storage block as a first type storage block in response to the instruction error correction value of the data in the storage block satisfying a preset condition when the read data operation is performed from the storage block, wherein the first type storage block is used for a first operation set; and determines the storage block as a second type storage block in response to the instruction error correction value of the data in the storage block not satisfying the preset condition, wherein the second type storage block is used for a second operation set, and the second operation set is partially different from the first operation set.

[0064] For the convenience of understanding, the data writing of the present application is exemplified, as shown in FIG. 5, which is a flow diagram of the data writing of an embodiment of the present application. When the host device 20 initiates a data writing command, the storage device 10 responds to the write instruction and performs a data writing operation on the storage block in the storage device 10, and the specific steps are as follows:

[0066] One of the determination results of step S51 is that the storage block is a first type storage block, and step S52 is performed.

[0067] The other of the determination results of step S51 is that the storage block is not a first type storage block, and step S53 is performed.

[0068] S52: Perform the data writing operation. In response to the storage block being determined as a first type storage block, perform the data writing operation with the host device 20 on the storage block.

[0069] S53: Do not participate in performing the data writing operation.
