10-nm SRAM Design Using Gate-Modulated Self-Collapse Write-Assist Enabling 175-mV V MIN Reduction With Negligible Active Power Overhead

A 21-Mb/mm2SRAM design using 0.0367-um2HCC bitcell on a 10-nm CMOS technology is presented. Gate-modulated selfcollapse (GSC) write-assist is utilized to enable 175 mV VMIN reduction with negligible active energy overhead, and a modest 5.5% array area overhead on a 256-Kb instance. Compared to NBL and TVC write-assist techniques, GSC delivers comparable VMIN improvement across a wide frequency range with 31%-108% write energy reduction.
