SEMICONDUCTOR DEVICE AND SEMICONDUCTOR MEMORY

摘要

PROBLEM TO BE SOLVED: To provide a semiconductor device in which the increment of chip area is small and which is provided with a high speed input initial stage latch. SOLUTION: A semiconductor device comprises: a first latch for receiving an input signal and holding the input signal for only a half cycle period of a first clock signal; a delay element connected to the output of the first latch; a second latch connected to the output of the delay element and holding a signal supplied from the delay element for only a half cycle period of a second clock signal; and a circuit for adjusting at least one of the timings of the first clock signal and the second clock signal so that a signal latched with the first latch in the half cycle of the first clock signal is latched by the second latch through the delay element in the half cycle period of a succeeding second clock signal.
