SEMICONDUCTOR STORAGE DEVICE, AND, DATA PROCESSING METHOD

PROBLEM TO BE SOLVED: To preferably provide an erasure mode in a system side for non-volatile even though a mode for erasure is not necessary because read-write can be performed randomly in a nonvolatile RAM and to preferably perform an erasure operation with low power and at a high speed.SOLUTION:...

description	PROBLEM TO BE SOLVED: To preferably provide an erasure mode in a system side for non-volatile even though a mode for erasure is not necessary because read-write can be performed randomly in a nonvolatile RAM and to preferably perform an erasure operation with low power and at a high speed.SOLUTION: A semiconductor storage device has memory cell arrays COA, DTA including a plurality of memory cells MC respectively having a magnetic resistance element, writes a series of data in the memory cell arrays COA, DTA, and performs an erasure operation by writing prescribed data only in the memory cell array COA during erasure.
