ABSTRACT:
A semiconductor device having a delay drift compensation circuit that compensates for a delay drift caused by temperature and voltage variations in a clock tree includes a clock driver having an output port, a first circuit having an input port, a first signal path between the output port of the clock driver and the input port of the first circuit and a first delay drift compensation circuit. The first delay drift compensation circuit, which is coupled with the first signal path, reduces a delay time of the first signal path when a power supply voltage increases, and increases the delay time of the first signal path when a temperature increases.
