Abstract
A semiconductor storage device of the present invention includes a unit for determining a pulse width by using a command input signal as a start point and thereby making a sense-amplifier activation signal or a latch capture signal of a synchronous mask ROM synchronize with activation or inactivation of a clock signal after cycles corresponding to the number of clocks of a set latency to generate timing.
