Abstract
A synchronous dynamic random access memory (SDRAM) (,) is disclosed. The SDRAM (,) operates in synchronism with differential clock signals (CLK and /CLK). A timing and control circuit (,) compares the complementary differential clock signals (CLK and /CLK) to generate an internal clock signal (CLKI). By comparing the differential clock signals (CLK and /CLK) to generate the internal clock signal (CLKI), the preferred embodiment can compensate for degradations in the differential clock signals (CLK and /CLK). In addition, by utilizing the internal timing signal (CLKI) the preferred embodiment does not have to employ more complex circuits that must operate in synchronism with the edges of both differential clock signals (CLK and /CLK).
