Abstract: An operation method performed at a nonvolatile memory device may include receiving a program command and an address from an external device through a data signal (DQ), receiving a specific pattern from the external device through the data signal and a data strobe signal (DQS) synchronized with the data signal in a pattern period, receiving user data from the external device through the data signal and the data strobe signal in a data period, and selectively performing a program operation on the user data or a recovery operation based on a determination of whether the specific pattern matches with a particular pattern. A rising edge or a falling edge of the data strobe signal may be aligned with a left edge or a right edge of a window of the data signal in the pattern period.

Abstract: A storage device includes a nonvolatile memory and a memory controller. The nonvolatile memory performs read, write, and erase operations. The memory controller operates in an operating mode where the memory controller exchanges a voltage signal, set to a reference voltage level within an allowable range, with the nonvolatile memory or receives the voltage signal from an external device. When operating in the operating mode, the memory controller optimizes an operating frequency of the nonvolatile memory depending on a voltage level of the voltage signal and a temperature.

Abstract: A storage device including a nonvolatile memory device including memory blocks and a controller connected with the nonvolatile memory device through data input and output lines and a data strobe line may be provided. The nonvolatile memory device and the controller may be configured to perform training on the data input and output lines by adjusting a delay of a data strobe signal sent through the data strobe line and adjust delays of the data input and output lines based on the training result.
