Disclosed is a read timing generation circuit, capable of reducing dynamic power consumption. After a multi-bit address Add, Add, . . . , and AddN passes through an address change monitoring unit (), a response pulse signal corresponding the address is generated. After the response pulse signal passes through an address trigger determination unit (), a single trigger determination signal ATDPRE is generated. The single trigger determination signal ATDPRE passes through an ATD timing generation unit () and a post-timing generation unit (), thereby forming a read timing generation circuit in a serial link and generating corresponding read timing. Compared with the conventional read timing generation circuit in which each bit of an address signal corresponds to a stage of structures to execute the trigger, ATD control timing output, and ATD determination process separately, the present invention greatly reduces the total dynamic power consumption of the circuit.

Disclosed is a multi-phase clock signal generation circuit including two circuit blocks, each of which includes a cross-coupled structure and two delay units, and the delay units are adjustable. One circuit block (MD) includes two NMOS transistors, two PMOS transistors, and two delay units, and the other circuit block (MD) may include two NMOS transistors, two PMOS transistors, and two delay units. The circuit can generate clock signals with respective phases whose relationship is relatively independent of integration process, operating voltage and temperature, thereby allowing guaranteed efficiency for a multi-phase charge pump.
