Patent ID: 8582392

Claim:
A method of performing a read operation in a non-volatile memory device, the method comprising: receiving a read control signal at a terminal of the memory device, the read control signal comprising an alternating sequence of first and second edges, the read control signal controlling an access time when a sequential data output operation is enabled in the non-volatile memory device, the first edges being one of rising edges and falling edges of the read control signal and the second edges being the other of rising and falling edges of the read control signal; generating a data strobe signal by delaying the read control signal, the data strobe signal comprising an alternating sequence of third and fourth edges, the third edges being one of rising edges and falling edges of the data strobe signal and the fourth edges being the other of rising and falling edges of the data strobe signal; sequentially outputting first and second data in response to one of the first edges and one of the second edges of the read control signal, respectively; and outputting the data strobe signal concurrently with outputting the first and second data, wherein the output of the first data is aligned with one of the third edges of the data strobe signal, wherein the output of the second data is aligned with one of the fourth edges of the data strobe signal, and wherein the alternating sequence of first and second edges of the read control signal is received only during the data output operation of the non-volatile memory.
