Abstract

A clock control circuit for sequentially enabling the clock input terminal of a number of groups of shift register stages for reducing the power consumption. The groups are seccessively activated, and the groups currently not in operation are made not to consume power. During changeover between adjacent groups of shift register stages, the clocks for the different groups overlap to insure stable operation.
