The newly proposed memory cell is consisted with a PCM for data storage and a MOS transistor connected in parallel. This memory cell is connected in series for realizing the chain structure. Cell structure, the design method for realizing stable read and write operation, and core circuit for the stacked type chain PRAM have been described. Newly proposed memory cell has been designed to adopt BiCS (Bit Cost Scalable) process technology for realizing low-cost memory. The design of the resistance of PCM and the pass transistor is key issue for realizing stable operation. For designing the row decoder, the circuit concept of the stacked FeRAM with the NAND structure cell has been successfully adopted with SGT. The newly proposed stacked type chain PRAM is a promising candidate for realizing high-speed and low-power future non-volatile semiconductor memory.本誌: 電気学会論文誌C（電子・情報・システム部門誌） Vol.133 No.5 （2013） 特集：新たな産業への応用が進む無線通信技術本誌掲載ページ: 937-946 p原稿種別: 論文／日本語電子版へのリンク: https://www.jstage.jst.go.jp/article/ieejeiss/133/5/133_937/_article/-char/ja/
