Abstract :
A one-transistor memory cell on silicon-on-insulator, called floating body cell (FBC), has been developed for high density embedded DRAM applications. The functionality of a 128Mb FBC DRAM using fully compatible 90nm CMOS technology has been successfully demonstrated. The memory cell design, such as fully-depleted (FD) operation with substrate-bias, and the process integration, such as well and Cu wiring, are reviewed. The scalability and future challenge of FBC technology are discussed as well
