ABSTRACT:
The present disclosure includes methods, and circuits, for operating a memory device. One method embodiment for operating a memory device includes controlling data transfer through a memory interface in an asynchronous mode by writing data to the memory device at least partially in response to a write enable signal on a first interface contact, and reading data from the memory device at least partially in response to a read enable signal on a second interface contact. The method further includes controlling data transfer in a synchronous mode by transferring data at least partially in response to a clock signal on the first interface contact, and providing a bidirectional data strobe signal on an interface contact not utilized in the asynchronous mode.
