Abstract
This paper describes a 64-entry × 32b 1-read, 1-write ported register file with measured 8.3GHz operation consuming 83mW, fabricated in 1.0V 32nm CMOS. Contention-free shared keeper circuits combined with variation tolerant dual-ended transmission gate write memory cells enable 300mV Vcc-min reduction and measured scalable near-threshold voltage operation to 340mV with energy efficiency of 550GOPS/W.
