Abstract
A semiconductor memory device includes a comparator that outputs a signal switched in synchronism with a read enable signal from outside and outputs the signal, and a correction circuit that adjusts the duty cycle of the signal. The correction circuit includes a variable current source connected to a first output portion of the comparator, and a variable current source connected to a second output portion of the comparator, and adjusts the amounts of current output from the current sources to adjust the duty cycles of signals.
