Memory system

Abstract

One embodiment provides a memory system including a controller capable of reliably controlling memory cells. A memory system according to an embodiment includes: a memory cell including: a memory cell array including a plurality of memory cells and divided into a plurality of memory cell blocks; and a driving circuit driving the plurality of memory cells, and a controller that controls the memory unit. Each of the plurality of memory cells includes a resistance change memory element and a switching element connected in series with the resistance change memory element. The controller is configured to control the memory cells such that the number of predetermined accesses to each of the plurality of memory cell blocks increases or decreases in accordance with the distance from the drive circuit to each of the plurality of memory cell blocks.
