A 0.5V, 400MHz, V/sub 00/-hopping processor with zero-V/sub TH/ FD-SOI technology

A 0.5V, 400MHz, 3.5mW, 16b RISC processor with a 0.25/spl mu/m, dual V/sub T/, fully-depleted SOI technology is presented. Zero V/sub T/ is used in logic for high speed while memories and register files adopt a higher V/sub 00/ and V/sub T/ to suppress leakage. Experimental results show that V/sub 00/-hopping is effective in leakage dominant environments.
