A novel DRAM cell based on floating junction gate (FJG) concept is investigated for its extended applications. Compared to the two-transistor floating gate DRAM cell, the new memory cell investigated in the present work has a much simpler configuration with only one transistor. Besides, its write speed is improved by introducing an integrated gated-diode so that state "1" can be self-refreshable. In this paper, the device configuration, the DRAM application feasibility, the self-refreshing ability, and the non-destructive read are explored. In addition, extended applications of the DRAM cell using the FJG concept will be discussed. (C) 2010 Elsevier Ltd. All rights reserved.
