More Information
Summary:A memory system may include a nonvolatile memory device and a controller. The nonvolatile memory device may include a data area and a device information area, the device information area being inaccessible accessed by a host. The controller may be configured to perform the training operation with respect to a data signal transmitted to or received from the nonvolatile memory device based on training information stored in the device information area. The controller may be configured to select one of a first training operation and a second training operation based on an identification code of the training information, and to perform the selected one of the first training operation based on a rooted training code generated by the controller and the second training operation based on a dynamic training code of the training information, the second training operation including performing a fewer number of searches than the first training operation.
