NONVOLATILE SEMICONDUCTOR MEMORY

摘要

PROBLEM TO BE SOLVED: To provide a nonvolatile semiconductor memory device for attaining a low power consumption while securing a stable reset of a selection memory cell. SOLUTION: The nonvolatile semiconductor memory device includes: a plurality of first wiring and second wiring intersecting each other; a memory cell array including the plurality of memory cells connected to each intersection part of the plurality of first wiring and second wiring; and a first wiring control circuit and second wiring control circuit for respectively selecting the first wiring and second wiring to supply voltage and current required for a reset operation or set operation of the memory cells. The first wiring control circuit supplies an unselected voltage according to a distance between the unselected first wiring and the second wiring control circuit to the unselected first wiring.
