A high-speed CMOS/SOS 4K word/spl times/1 bit static RAM is described. The RAM features a MoSi/SUB 2/ gate CMOS/SOS technology with 2 /spl mu/m gate length and 500 /spl Aring/ thick gate oxide. Performance advantage of SOS over bulk is discussed for the scaled-down MOS LSI with 1-2 /spl mu/m gate. A standard 6-transistor CMOS cell and a two-stage sense amplifier scheme are utilized. In spite of the rather conservative 3.5 /spl mu/m design rule except for the 2 /spl mu/m gate length, the cell…
