Abstract

A memory capable of suppressing disturbance causing disappearance of data in a nonselected memory cell is provided. This memory comprises a memory cell array including a bit line, a word line arranged to intersect with the bit line and memory cells connected between the bit line and the word line, for accessing a selected memory cell thereby deteriorating a remanent polarization in an arbitrary memory cell and thereafter performing recovery for recovering all memory cells to remanent polarizations immediately after a write operation or remanent polarizations subjected to single application of a voltage applied to a nonselected memory cell in the access.
