Abstract
A memory module includes a clock driver configured to receive an external clock through a module pin and configured to generate an internal clock that is transmitted to memory chips by delaying a division clock that is generated from the external clock by a clock delay interval. The clock driver adjusts the clock delay interval by comparing the phase of the division clock and the phase of a feedback division clock that is generated from the internal clock.
