Description

Technical Field

[0001] The present disclosure relates to the technical field of non-volatile memory, and in particular to a Nor Flash (a non-volatile flash memory technology) and a page programming method and system thereof. Background Art

[0002] Today, the booming development of technologies such as the Internet of Things, artificial intelligence, and driverless driving is driving the rapid growth of the embedded storage market. Nor Flash storage technology is a non-volatile memory technology that is mainly used to store program code and data. Compared with traditional electrically erasable programmable read-only memory (EEPROM), it has the advantages of large capacity, small size, low power consumption, stable performance, and high localization rate. Therefore, Nor Flash is widely used in various intelligent fields, including motherboard basic input and output systems, digital set-top boxes, home gateways, routers, the Internet of Things, automotive electronics, wearable devices, security monitoring, and artificial intelligence. Its versatility and reliability make our lives more convenient and intelligent.

[0003] Nor Flash has the characteristics of fast reading speed, but slow programming speed and erasing speed. Therefore, in the development process of Nor Flash, its programming speed needs to be continuously optimized. In the traditional Nor Flash programming process, the programming operation is performed in pages, that is, full page programming. No matter how much programming data is, Nor Flash will operate on the entire page corresponding to the programming address. When the programming data is small, this programming method will cause the Nor Flash programming time to be too long, increase programming power consumption, and shorten the service life of Nor Flash.

[0059] The present disclosure is further described below by way of examples, but the present disclosure is not limited to the scope of the examples.

[0060] Prefixes such as "first" and "second" are used in the embodiments of the present disclosure only to distinguish different description objects, and have no limiting effect on the position, order, priority, quantity or content of the described objects. The use of prefixes such as ordinal numbers to distinguish description objects in the embodiments of the present disclosure does not constitute a limitation on the described objects. For the statement of the described objects, please refer to the description in the context of the embodiments, and no unnecessary limitation should be constituted due to the use of such prefixes. In addition, in the description of the present embodiment, unless otherwise specified, the meaning of "plurality" is two or more.

[0061] In the embodiments of the present disclosure, the collection, storage, use, processing, transmission, provision and disclosure of user personal information involved are in compliance with the provisions of relevant laws and regulations and do not violate public order and good morals.

[0062] Example 1

[0063] This embodiment provides a page programming method of Nor Flash, wherein Nor Flash includes multiple storage pages, such as Figure 1 As shown, the page programming method of Nor Flash includes:

[0064] S1. Get the programming command, which includes the number of programming bytes and the programming start address.

[0065] S2. Set the full page programming enable signal based on the number of programming bytes.

[0066] S3. If the full page programming enable signal is false, a partial page programming operation is performed on the target storage page corresponding to the programming start address.

[0067] Specifically, the program command includes but is not limited to the program byte number and the program start address.

[0068] In Nor Flash, page is a common unit of programming operation. Existing Nor Flash is programmed by page, so no matter how much programming data is, Nor Flash will operate on the entire page corresponding to the programming address, and cannot use the write data capacity to the maximum efficiency for writing operations, resulting in low efficiency of programming operations.

[0069] The page programming method of the Nor Flash of the present embodiment obtains the programming byte number and the programming start address in the programming command, and sets the full page programming enable signal based on the programming byte number. If the full page programming enable signal is false, a partial page programming operation is performed on the target storage page corresponding to the programming start address. Only the storage cells that need to be programmed need to be selected for programming, which can not only shorten the programming time but also reduce the programming power consumption. At the same time, all page storage cells will not be selected at a high frequency to apply programming voltage pulses to raise the threshold voltage, which can extend the service life of the Nor Flash.

[0070] In an optional embodiment, if Figure 2 As shown, the above step S2 includes:

[0071] S21, determining whether the number of programmed bytes is less than the preset number of bytes.

[0072] If yes, then execute step S22, if no, then execute step S23;

[0073] S22, set the full page programming enable signal to false.

[0074] S23, set the full page programming enable signal to true.

[0075] The preset number of bytes is smaller than the number of bytes of the entire page.

[0076] The number of bytes of a whole page in Nor Flash is 256 bytes, and the preset number of bytes is smaller than the number of bytes of the whole page, that is, the preset number of bytes can be any value between 1-255, for example, it can be 240 bytes.

[0077] For example, the full page programming enable signal may be set to 0, ie, the full page programming enable signal is false; or the full page programming enable signal may be set to 1, ie, the full page programming enable signal is true.

[0078] The page programming method of Nor Flash in this embodiment determines whether to perform a partial page programming operation by judging the relationship between the programming byte number and the preset byte number, and can quickly distinguish whether a partial page programming operation or a full page programming operation is required.

[0079] In an optional embodiment, if Figure 3 As shown, the above step S3 includes:

[0080] S31 . Perform a partial page programming operation on a target storage page corresponding to a programming start address.

[0081] The above step S3 includes:

[0082] S0. Determine whether the full page programming enable signal is false.

[0083] If yes, execute step S31.

[0084] In an optional embodiment, if Figure 4 As shown, the above step S31 includes:

[0085] S311 , obtaining the end address to be programmed and the data to be programmed corresponding to the programming command.

[0086] S312: Based on the programming start address, the end address to be programmed, and the data to be programmed, a partial page pre-verification operation is performed on the target storage page.

[0087] S313: After the partial page pre-verification operation is completed, a data programming operation is performed on the target storage page based on the programming start address, the end address to be programmed, and the data to be programmed.

[0088] S314: After the data programming operation is completed, a partial page post-verification operation is performed on the target storage page based on the programming start address, the end address to be programmed, and the data to be programmed.

[0089] S315 , after the partial page post-verification operation is completed, determine that the partial page programming operation is successful.

[0090] The partial page programming operation mainly consists of a partial page pre-verification operation, a data programming operation and a partial page post-verification operation. If the full page programming enable signal is false, a partial page programming operation is required for the target storage page corresponding to the programming start address.

[0091] Specifically, a partial page pre-verification operation is first performed on the target storage page to determine whether the target storage page is in a programmable state; after the partial page pre-verification operation is completed, a data programming operation is performed on the target storage page, that is, a data writing operation is performed on the target storage page; after the data programming operation is completed, a partial page post-verification operation is performed on the target storage page to verify whether the written data corresponds to the data to be programmed; after the partial page post-verification operation is completed, it is determined that the partial page programming operation is successful.

[0092] In an optional embodiment, if Figure 5 As shown, the above step S312 includes:

[0093] S3121. Obtain the original data currently stored in each programming address between the programming start address and the to-be-programmed end address.

[0094] S3122, obtaining the data to be programmed corresponding to each programming address.

[0095] S3123, determine whether the data to be programmed and the original data corresponding to the same programming address meet the preset data state.

[0096] If yes, execute step S3124, if no, execute step S3125.

[0097] S3124. Determine that the partial page pre-verification operation is completed.

[0098] S3125, end the programming operation.

[0099] After step S3124 is executed, step S313 is executed; that is, after the partial page pre-verification operation is completed, a data programming operation is performed on the target storage page based on the programming start address, the end address to be programmed and the data to be programmed.

[0100] The preset data state is that the original data is 1 and the data to be programmed is 0.

[0101] When the original data currently stored in the programming address is 1, it means that the programming address is in a programmable state. When the data to be programmed corresponding to the programming address is 0, it means that the programming address needs to be programmed. When the original data corresponding to a programming address is 1 and the data to be programmed is 0, it can be determined that the programming address is in a programmable state and needs to be programmed, thereby determining that the partial page pre-verification operation is completed.

[0102] In an optional embodiment, if Figure 6As shown, after the above step S313, the following steps are also included:

[0103] S316: Determine whether the actual programming end address is equal to the to-be-programmed end address.

[0104] If yes, execute step S317; if no, execute step S318.

[0105] S317 , determine that the data programming operation is completed.

[0106] S318, performing data programming operations on each programming address between the actual programming end address and the to-be-programmed end address until the actual programming end address is equal to the to-be-programmed end address.

[0107] After step S317 is executed, step S314 is executed, that is, after the data programming operation is completed, a partial page post-verification operation is performed on the target storage page based on the programming start address, the end address to be programmed and the data to be programmed.

[0108] If the actual programming end address is equal to the to-be-programmed end address, it indicates that the data programming operation is completed; if the actual programming end address is not equal to the to-be-programmed end address, it indicates that the data programming operation is not completed, for example, the data programming operation may be only 80% completed. Therefore, it is necessary to continue the data programming operation. Specifically, the data programming operation is performed on each programming address between the actual programming end address and the to-be-programmed end address until the actual programming end address is equal to the to-be-programmed end address to ensure that the data programming operation is 100% completed.

[0109] In an optional embodiment, if Figure 7 As shown, the above step S313 includes:

[0110] S3131. Determine that the partial page pre-verification operation is completed.

[0111] S3132: Based on the programming start address, the end address to be programmed, and the data to be programmed, perform a data programming operation on the target storage page.

[0112] The above step S314 includes:

[0113] S3141. After the data programming operation is completed, obtain the actual programming data in each programming address between the programming start address and the actual programming end address.

[0114] S3142, obtaining the data to be programmed corresponding to each programming address.

[0115] S3143. Determine whether the actual programming data corresponding to the same programming address is equal to the data to be programmed.

[0116] If so, execute step S3144; if not, return to step S3132.

[0117] S3144. After confirming some pages, the verification operation is completed.

[0118] If the actual programming data corresponding to the same programming address is not equal to the data to be programmed, then based on the programming start address, the end address to be programmed and the data to be programmed, the step of performing data programming operation on the target storage page. When the actual programming data corresponding to the same programming address is not equal to the data to be programmed, it indicates that the data programming operation has not passed, the data writing has failed, and the data programming operation needs to be continued.

[0119] If the actual programming data corresponding to the same programming address is equal to the data to be programmed, it indicates that the partial page post-verification operation is completed and the partial page programming operation is successful.

[0120] In an optional embodiment, if Figure 2 As shown, the page programming method of Nor Flash also includes:

[0121] S4. If the full page programming enable signal is true, a full page programming operation is performed on the target storage page corresponding to the programming start address.

[0122] The full page programming operation is a mature technology in this field, and the specific content will not be repeated here.

[0123] Figure 8 The eighth flow chart of the page programming method of Nor Flash provided in the first embodiment of the present disclosure is as follows: Figure 8 As shown, when a programming command is received, the Nor Flash chip will be initialized internally, and the programming start address in the programming command will be recorded at the same time, and then it will be determined whether the number of programming bytes is less than the preset number of bytes. If so, the full page programming enable signal is set to false, if not, the full page programming enable signal is set to true; then it is determined whether the full page programming enable signal is false, if not, a full page programming operation is performed, and the page programming is terminated after the full page programming operation is successful; if so, a partial page programming operation is performed. Specifically, a partial page pre-verification operation is performed first to determine whether the partial page pre-verification operation is completed, if so, a data programming operation is performed, if not, the page programming is terminated; then it is determined whether the data programming operation is completed, if so, a partial page post-verification operation is performed, if not, the data programming operation is continued until the data programming operation is completed, and then it is determined whether the partial page post-verification operation is completed, if so, the partial page programming operation is successful, and the page programming is terminated, if not, the data programming operation is returned to be executed until the partial page programming operation is successful. For details on how to determine whether the partial page pre-verification operation is completed, whether the data programming operation is completed, and whether the partial page post-verification operation is completed, see the above-mentioned related text description and Figures 1 to 7 That’s it, I won’t go into details here.
