Current-mode approach in register file has the great advantage of high operation speed with low power consumption. Under 0.35- μ m CMOS technology, we present a 1.85-ns read access, 32 X 32-bit, five-port register file in which a modified current-sense amplifier is used. The delay match circuit and TSPC-FF are also used to improve speed. Energy saving is achieved by current mode and other key ideas. Simulation results show it consumes 640mW at 500MHz 3.3V. It can still work at 2.3V with 350MHz 300mW.
