Low power shift register latch

摘要

A combination of logic circuits perform logical operations on data and include a plurality of shift register latches. Each shift register latch includes a latch means for the storing of data, an isolation means for isolating the latch means from data and clock signals connected logic circuits when the isolation means is at a first state, and for conducting data to the latch means when the isolation means is at a second state. Each shift register latch also includes a power reduction means for reducing the power consumed by the isolation means and the latch means.
