1. semiconductor storage unit comprises:

  • Clock buffer is used to receive external system clock with the output internal clocking;

    Locked loop unit is used for delay through controlling this internal clocking so that data output time and external system clock output delay synchronously locking internal clocking;

    Data output buffer is used for data and delay lock internal clocking synchronously, exports these data thus;

    AndThe clock buffer control unit;

    Be used to respond last running status and produce the enabling signal of the ON/OFF conversion of controlling clock buffer, to allow said enabling signal to have the different logical level in response to the identical control signal of logic level according to last running status.
