ABSTRACT:
A purpose of the invention is to immediately return the operation in a flash memory module from low power consumption mode to regular mode. A flash memory controller having memory that stores an address translation table for translating between a logical page address and a physical page address in the flash memory chip controls regular mode and low power consumption mode of operating at lower power consumption than in regular mode by halting operation, or decreasing power supply voltage or lowering operating frequency. A flash memory module having the flash memory controller verifies data in the address translation table while low power consumption mode is set.
