  • Shift register
    Patent number: 6765980
    Abstract: A shift register with low power consumption has memory circuits 151-15N connected in series, gate circuits in memory circuits 152n−1 in the odd-numbered locations become conductive when clock signal CK is high, and gate circuits in memory circuits 152n in the even-numbered locations become conductive when clock signal CK is low, wherein data signals S input are latched for output when the gate circuits are shut off. The circuit configuration is simplified. The Shift register operates every one half of the cycle of clock signal CK, allowing the frequency of clock signal to be reduced by half, resulting in reduced power consumption.
