Abstract
A random access memory includes a first circuit configured to receive a strobe signal and provide pulses in response to transitions in the strobe signal, and a second circuit configured to receive the strobe signal to latch data into the second circuit in response to the strobe signal, and to receive the pulses to re-latch the latched data into the second circuit after the transitions in the strobe signal. The first circuit includes an enable circuit configured to provide an enable signal and a buffer circuit configured to receive the strobe signal and the enable signal and provide the pulses in response to the enable signal and the strobe signal. The enable circuit is configured to receive the pulses from the buffer circuit and stop providing the enable signal to the buffer circuit in response to receiving the pulses.
