Claim Text:
1. A method of reading a nonvolatile memory device including a plurality of nonvolatile memory cells, the method comprising: receiving a read command and a read address; in response to the read command, reading data from first memory cells corresponding to the read address among the plurality of nonvolatile memory cells; receiving a read enable signal, the read enable signal being toggled after the receiving the read command and the read address; generating a strobe signal based on the read enable signal; outputting the strobe signal to an external device; and outputting, to the external device, the data read from the first memory cells in synchronization with the strobe signal in response to a latency value, the latency value being corresponding to the number of toggling of the strobe signal between the receiving the read command and the read address and the outputting the data, the latency value being zero or a positive integer, wherein the read enable signal remains constant while the read command and the read address are received, and the latency value is stored in the nonvolatile memory device and is programmable with a set command.
