Abstract
In a storage system using flash EEPROMs, a memory module is composed of a plurality of memory blocks arranged in units of in-unison erase blocks. Some of the memory blocks are used as management tables storing management information for managing address allocation of each memory block and the number of rewrites for each memory block. A memory controller reads the management information from the management table at the system start-up, and based on the management information, controls the read/write access to each memory block.
