A technique for compensating for duty cycle distortion in an output data
signal generated by a synchronous dynamic random access memory device
(SDRAM) is provided. The output latch of the SDRAM is driven by an output
clock signal generated by a delay lock loop (DLL). The output clock
signal is phase-shifted relative to a reference clock signal received by
the DLL such that the data removed from the output latch is synchronous
with the reference clock signal. Further the duty cycle of the output
clock signal is adjusted in a phase inverse relationship to the duty
cycle distortion introduced by the output latch. As a result, the output
data signal has reduced duty cycle distortion.
