Abstract :
A Monte Carlo simulation shows that a DRAM using the floating body cell (FEC) realizes a 333MHz high-speed random cycle with an introduction of a symmetrical sense amplifier circuit and optimization of its current mirror ratio. Since the FEC DRAM having a superior affinity with logic LSI process is also shown to have its macro size smaller than the conventional 1T-1C DRAM, the FEC is a promising candidate for next generation embedded DRAM cells
