A novel self-refreshable capacitorless DRAM cell

A novel DRAM cell based on floating gate (FG) concept is investigated. Compared to the conventional two-transistor FG DRAM cells, this new memory cell has a much simpler configuration with only one transistor. Besides, its write speed is improved by introducing an integrated gated diode and state ldquo1rdquo can be self-refreshable. In this paper, the device configuration, the DRAM application feasibility, the self-refreshing ability, and the nondestructive read are discussed.
