A low-power multi port register file design using a low-swing strategy

a low-power register file is designed by using a low-swing strategy and modified NAND address decoders. The proposed low-swing strategy is based on the feedback scheme and uses dynamic logic to reduce the active feedback power.This method contains two parts：WRITE and READ strategy.In the WRITE low-swing scheme,the modified memory cell is used to support low-swing WRITE.The modified NAND decoder not only dissipates less power,but also enables a great deal of area reduction.Compared with the conventional single-ended register file,the low-swing strategy saves 34.5%and 51.15%bit-line power in WRITE and READ separately.The post simulation results indicate a 39.4%power improvement when the twelve ports are all busy.
