A circuit for latching data into a memory includes a receiver, a delay, and a selector. The receiver is configured for receiving a data signal, and the delay is configured to delay the data signal to provide a delayed data signal. The selector is configured to receive the delayed data signal, a data strobe signal, and an inverted data strobe signal and provide a first strobe signal and a second strobe signal in response to the delayed data signal, the data strobe signal, and the inverted data strobe signal. Rising edge data is latched into the memory in response to the first strobe signal and falling edge data is latched into the memory in response to the second strobe signal.
