RESISTANCE-CHANGING MEMORY DEVICE

摘要

A resistance-changing memory device has a cell array having memory cells, each of which stores as data a reversibly settable resistance value, a sense amplifier for reading data from a selected memory cell in the cell array, and a voltage generator circuit which generates, after having read data of the selected memory cell, a voltage pulse for convergence of a resistive state of this selected memory cell in accordance with the read data.
