Memory system and constructing method of logical block

摘要

According to one embodiment, a memory system includes a bit-error-rate manager configured to manage information associated with a bit error rate for each physical block, a logical-block constructing unit configured to construct a logical block based on the information associated with the bit error rate, and a block manager configured to manage the correspondence between the logical block constructed by the logical-block constructing unit and the physical blocks. The logical block is a collection of a plurality of physical blocks.
