A multi-stage replica bitline technique for reducing access time by suppressing enable timing variation of a sense amplifier was developed. Applied to a 288-kbit SRAM of the 40-nm process node, this technique achieves 6.1% access time reduction by reducing the sense-amplifier timing variation by 43%.
