摘要:
The purpose of the present invention is to improve a rewriting transmission rate and reliability of a phase change memory. To attain the purpose, a plurality of phase change memory cells (SMC or USMC) which are provided in series between a word line (2) and a bit line (3) and have a selection element and a storage element that are parallel connected with each other are entirely set, and after that, a part of the cells corresponding to a data pattern is reset. Alternatively, the reverse of the operation is carried out.
