Volentine & Whitt, PLLC
Storage device including nonvolatile memory and memory controller and operating method of retiming circuit interfacing communication between nonvolatile memory and memory controller
A storage device includes a nonvolatile memory, and a memory controller adapted to control the nonvolatile memory and to transmit a first timing signal to the nonvolatile memory at a read operation. The nonvolatile memory includes a nonvolatile memory device adapted to output read data and a second timing signal in response to the first timing signal, and a retiming circuit adapted to detect a locking delay according to the first timing signal, to produce a third timing signal from the second timing signal using the detected locking delay, to retime the read data by latching the read data in synchronization with the third timing signal and to output the third timing signal and the retimed read data to the memory controller.
