Abstract: A semiconductor memory device, which refreshes memory cells to retain data, has a first refresh mode and a second refresh mode. The first refresh mode is a mode for refreshing all of the memory cells, and the second refresh mode is a mode for refreshing a part of the memory cells. By refreshing only designated areas where data must be retained, power consumption in a refresh operation can be reduced, drastically cutting power consumption in a power-down mode.

Abstract: The present invention omits a variable delay circuit (10 in FIG. 1) inside a DLL circuit, and instead, creates a timing synchronization circuit, which generates a second reference clock. The timing synchronization circuit shifts the phase of a first reference clock generated by a frequency divider to the timing of a timing signal generated from the other variable delay circuit so that the second reference clock matches to the timing signal. Then, a phase comparator compares the divided first reference clock to a variable clock that delays the second reference clock, and controls the delay time of the variable delay circuit so that both clocks are in phase. As a result, one variable delay circuit can be omitted, and a DLL circuit that uses a divided clock can be configured.
