Abstract
A semiconductor device that receives input data synchronized with a first clock signal and generates output data synchronized with a second clock signal, includes a clock delay circuit that generates first and second delay clock signals, first and second synchronized retrieval circuits that respectively retrieve the input data at timings when each of logical values of the second clock signal and second delay clock signal being switched, to respectively obtain first and second retrieved data, and a clock value retrieval circuit that retrieves a value of the first clock signal at timings when the second clock signal and first delay clock signal respectively switch from the first logical value to the second logical value, to respectively output first and second clock values, and an output circuit that outputs, as the output data, the first or second retrieved data, depending on a value of the first and second clock values.
