NON-VOLATILE SEMICONDUCTOR STORAGE APPARATUS

摘要

According to one embodiment, apparatus includes non-volatile memory chips, and a first controller which executes processing for reading first valid data stored in a first storage region of a first non-volatile memory chip in the non-volatile memory chips, processing for storing the first valid data in a buffer memory, processing for writing the first valid data stored in the buffer memory in a second storage region of the first non-volatile memory chip, and processing for erasing data stored in the first storage region. Each of the non-volatile memory chips comprises erase blocks. Each erase block includes write blocks. Each of the first storage region and the second storage region includes at least one erase block.
