description This paper describes a half-swing pulse-mode gate family that uses reduced input signal swing without sacrificing performance. These gates are well suited for decreasing the power in SRAM decoders and write circuits by reducing the signal swing on high-capacitance predecode lines, write bus lines, and bit lines. Charge recycling between positive and negative half-swing pulses further reduces the power dissipation. These techniques are demonstrated in a 2-K/spl times/16-b SRAM fabricated in a 0.25-/spl mu/m dual-V/sub t/ CMOS technology that dissipates 0.9 mW operating at 1 V, 100 MHz, and room temperature. On-chip voltage samplers were used to probe internal nodes.
