Abstract
In a method of operating a storage device including a storage controller and a nonvolatile memory, the storage device is powered on based on an activation of an external power supply voltage. An establishment of communication with a host device is waited for, based on a link signal between the storage device and the host device. Without the establishment of communication with the host device, a retention enhancement operation is performed on the storage device by entering a retention enhancement mode and by providing at least one command from the storage controller to the nonvolatile memory.
