NAND flash memory storage data recovery apparatus {NAND flash memory storage data recovery apparatus}

The present invention relates to a NAND flash memory storage data recovery device for recovering data stored in NAND flash memory that cannot be used due to a controller error, etc.

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

Most data storage devices include at least one NAND flash memory, a controller that controls the NAND flash memory to enable writing, reading, and deleting of data in the NAND flash memory, and a controller that transmits data to the NAND flash memory through the controller. The input/output ports for inputting or outputting data stored in NAND flash memory are integrated into the printed circuit board.

NAND flash memory contains 1 to 4 outer chips, each with 4 to 8 inner chips, and is packaged in one of predetermined formats. Data is stored in the inner chips dependent on each outer chip under the control of a controller. Write, read, and delete functions are performed.

Meanwhile, if an error occurs in the controller of the data storage device, the data writing, reading, and deleting functions in the NAND flash memory are not performed properly, making it unusable.

If 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.

That is, after completely removing the NAND flash memory from the printed circuit board and installing it on data recovery equipment, a data recovery program with a controller function is used to recover the data stored in the NAND flash memory to another data storage device. A data recovery operation is being performed on the memory.

Here, NAND flash memory is largely divided into four types depending on the package type. To this end, a total of four types of data recovery methods are provided, each with a printed circuit board wired and wired to correspond to the type of NAND flash memory according to each package type. One of the devices is being used selectively.
