SEMICONDUCTOR MEMORY DEVICE

摘要

PROBLEM TO BE SOLVED: To prolong a life as a product by suppressing an effect of deviation in the use environment. SOLUTION: A semiconductor memory device 10 includes a memory array 11 having a plurality of memory cells MC which become the low-resistance state/high-resistance state according to "0" data/"1" data, and an allocation of the "0" data/"1" data and the low-resistance state/high-resistance state is changed over when a power is turned on.
