Description

NAND flash memory storage data recovery device

[0001] The present invention relates to a NAND flash memory storage data recovery device for recovering data stored in a NAND flash memory that is unusable due to a controller error or the like.

[0002] In general, NAND flash memory is a non-volatile memory that has both the advantages of ROM, which preserves data even when power is cut off, and RAM, which allows data to be easily written and erased. It is widely used in data storage devices including USB drives and external hard disks.

[0003] Most data storage devices have at least one NAND flash memory, a controller that controls the NAND flash memory to enable data writing, reading, and deleting functions in the NAND flash memory, and an input / output port for inputting data to the NAND flash memory or outputting data stored in the NAND flash memory through the controller, all of which are mounted on a printed circuit board.

[0004] And NAND flash memory is packaged in one of the predetermined formats, including 1 to 4 outer chips each having 4 to 8 inner chips, and data writing, reading, and deleting functions are performed in the inner chip dependent on each outer chip under the control of the controller.

[0005] Meanwhile, if an error occurs in the controller, the data storage device becomes unusable because the writing, reading, and deleting functions of data in the NAND flash memory are not performed properly.

[0006] In cases where the data storage device becomes unusable due to a controller error as described above, a data recovery operation must be performed to recover the data stored in the NAND flash memory.

[0007] That is, after completely removing the NAND flash memory from the printed circuit board and mounting it on data recovery equipment, a data recovery program with the function of a controller is used to perform data recovery on the NAND flash memory so that the data stored in the NAND flash memory can be recovered to another data storage device.

[0008] Here, NAND flash memory is broadly divided into four types according to the package type, and for this purpose, one of four types of data recovery equipment with printed circuit boards that are wired and connected corresponding to the form of NAND flash memory according to each package type is selectively used.

[0009] However, conventional data recovery equipment is manufactured by data recovery companies by selecting multiple printed circuit boards to correspond to the type of NAND flash memory, and then soldering and connecting the selected multiple printed circuit boards with multiple wires.

[0010] In other words, conventional data recovery equipment is made in a simple form with only the data recovery function as the focus, so the printed circuit board and wiring are all exposed to the outside and there is no case or cover to protect or conceal them, so there is a problem with greatly reduced durability.

[0011] Therefore, it is necessary to develop a data recovery device that can be conveniently used selectively without wiring or soldering work depending on the type of NAND flash memory, and that has a structure that enhances durability by not exposing the printed circuit board and wiring that make up the data recovery device to the outside.

[0012] The present invention has been invented to solve the above-mentioned problem, and the purpose of the present invention is to provide a NAND flash memory storage data recovery device, which comprises a socket unit in which a NAND flash memory to be recovered is detachably mounted, and at least one host unit detachably connected to the socket unit and providing a controller according to the package type of the NAND flash memory mounted on the socket unit, so that the device can be conveniently used by selectively combining without separate wiring and soldering work according to the type of NAND flash memory, and a printed circuit board and wiring for implementing a function are hidden from the outside so as not to be exposed, thereby enhancing durability.

[0013] The purpose of the present invention is not limited to the purpose mentioned above, and other purposes not mentioned can be sufficiently included in the purpose of the present invention while being clearly understood from the description below.

[0015] A detachable connection means may be further included for detachably connecting the host casing to each connection surface of the socket casing to electrically connect the base board and the host board.

[0016] The above detachable connection means may be composed of a plurality of amphoteric pin connectors provided on the base board and electrically connected to the second wiring circuit, a plurality of amphoteric pin connectors provided on the host board and electrically connected to the control circuit, and self-attaching members installed on each connection surface of the socket casing and one side of the host casing to be self-attached to each other.

[0017] The above host unit may further include a data transfer indicator lamp provided in the host casing to indicate a status in which data stored in the NAND flash memory is transferred to the terminal through the USB cable connected to the USB port according to the operation of the control circuit and the recovery program.

[0021] And since the number of host units connected to the socket unit can be adjusted to correspond to the package type of the NAND flash memory, data recovery operations can be smoothly performed regardless of the package type of the NAND flash memory.

[0022] In addition, when connecting a host unit to a socket unit, the convenience of use can be enhanced as the connection can be made at an accurate location through the action of the protrusions, grooves, and magnetic material.
