Introduction

Young Joon Choi is a notable inventor based in Gyeonggi-do, South Korea. He has made significant contributions to the field of data storage technology, holding 2 patents that focus on improving efficiency and reducing power consumption in storage devices.

Latest Patents

One of his latest patents is a "Data storing method and data storing apparatus for reducing power consumption in sudden power-off." This invention discloses a method performed by a controller that includes storing an attribute value of first data to be written to a nonvolatile memory device in a command queue. The method determines whether the first data is garbage collection data based on the attribute value when a power interruption occurs. It then writes the first data to the nonvolatile memory device according to the determination result.

Another significant patent is the "Method of operating storage device." This invention describes a method for operating a storage device that includes a NAND flash memory with memory cells grouped into blocks, each block divided into pages. The method involves loading a look-up table containing first read reference voltage sets corresponding to respective retention degradation stages of the NAND flash memory. The controller performs a read operation on the memory cells on a per-block basis using the appropriate reference voltage sets until all memory cells in a current block are correctly read.
