ABSTRACT:
A semiconductor device that operates with reduced power consumption having a clock transfer blocking circuit and an external data transfer blocking circuit that blocks a clock signal and a data signal from being transferred to a data output circuit when a data signal captured by a data capturing circuit is to be latched by a latch circuit. If however, the data signal captured is necessary for a later stage of the semiconductor device, then an internal data transfer blocking circuit blocks the data signal from being latched in the latch circuit, while the clock transfer blocking circuit and the external data transfer blocking circuit cause the captured clock signal and data signal to be output to the data output circuit.
