Abstract :
A register file leverages from a replica-based control unit to improve reliability, operate in a wide voltage range, and support two supply voltages. The main power supply can be stepped down to reduce power, or shut off for sleep mode. Access time is 1.4 ns and power dissipation is 220 mW at 500 MHz in 1.2 V, 0.11 /spl mu/m CMOS.
