Storage device including nonvolatile memory and memory controller and operating method of retiming circuit interfacing communication between nonvolatile memory and memory controller
First Claim
1. A storage device comprising:
- a nonvolatile memory; and
a memory controller configured to control the nonvolatile memory and configured to transmit a first timing signal to the nonvolatile memory at a read operation,wherein the nonvolatile memory comprises;
a nonvolatile memory device configured to output read data and a second timing signal in response to the first timing signal; and
a retiming circuit configured to detect a locking delay based on the first timing signal, configured to produce a third timing signal from the second timing signal using the detected locking delay, configured to retime the read data by latching the read data in synchronization with the third timing signal, and configured to output the third timing signal and the retimed read data to the memory controller.

Abstract
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.
