Abstract

A semiconductor device for high-speed reading and which has a high data-retention characteristic is provided. In a semiconductor device including a memory array having a plurality of memory cells provided at intersecting points of a plurality of word lines and a plurality of bit lines, where each memory cell includes an information memory section and a select element, information is programmed by a first pulse (reset operation) for programming information flowing in the bit line, a second pulse (set operation) different from the first pulse, and information is read by a third pulse (read operation), such that the current directions of the second pulse and the third pulse are opposite to each other.
