MEMORY SYSTEM

摘要

A memory system according to an embodiment of the present invention comprises: a data managing unit (120) is divided into a DRAM-layer managing unit (120a), a logical-NAND-layer managing unit (120b), and a physical-NAND-layer managing unit (120c) to independently perform management of a DRAM layer, a logical NAND layer, and a physical NAND layer using the respective managing units to thereby perform efficient block management.
