CONTROL METHOD FOR NONVOLATILE STORAGE DEVICE, AND MEMORY DEVICE

摘要

PROBLEM TO BE SOLVED: To accelerate the speed of access to the area of high access frequency with limited RAM capacity in a control method for a nonvolatile storage device in which a logical address and a physical address are made corresponding by an address translation table. SOLUTION: A nonvolatile storage device 1 is divided into a plurality of areas, the address translation table is generated on a RAM 2 for the unit of an area and with respect to at least one area of high access frequency, the address translation table is placed on the RAM 2 all the time but with respect to at least another area, the address translation table is created on the RAM 2 on the basis of an access history.
