Apparatus for adjusting delay of command signal path

Abstract:

An example apparatus includes a first circuit configured to generate a first enable signal based on a first clock signal and a first command signal, a second circuit configured to generate a second enable signal based on the first clock signal and a second command signal, a third circuit configured to generate a second clock signal based on the first clock signal when the first enable signal is activated, a fourth circuit configured to generate a third clock signal based on the first clock signal when the second enable signal is activated, a first latch circuit configured to latch the second command signal in response to the second clock signal to generate a third command signal, and a second latch circuit configured to latch the third command signal in response to the third clock signal to generate a fourth command signal.
