1. semiconductor storage unit comprises:

  • Clock buffer is used to receive external system clock and exports as internal clocking;

    Locked loop unit is used to control the delay of this internal clocking so that data output time and system clock are synchronous;

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

    AndThe clock buffer control unit, running status before being used to respond and produce the enabling signal of the ON/OFF conversion of control clock buffer.
