Abstract: A storage device includes a nonvolatile memory device, and a controller that reads first data from the nonvolatile memory device. When a number of first errors of the first data is not smaller than a first threshold value, the controller determines whether the first errors include timing errors arising from a variation of signal transmission timings between the nonvolatile memory device and the controller and performs a retraining operation on the signal transmission timings when the first errors include the timing errors.

Abstract: A memory system including a memory controller with channel interfaces connecting memory groups via channels. Each channel interface communicates control, address and/or data (CAD) signals to a channel-connected memory group synchronously with a slave clock derived from an input clock. The various slave clocks being uniquely generated by application of channel interface specific phase/frequency modulation or temporal delay, such that the respective CAD signals are characterized by skewed transition timing.
