    Abstract: In a method of operating a storage device including a plurality of storage regions, a first request is received. The first request is for a cryptographic erasure with respect to a first storage region. During a first time interval, a first encryption key corresponding to the first storage region is changed based on the first request. A second request is received. In response to receiving the second request within the first time interval, a region access signal is outputted. In response to determining, based on the region access signal, that the second request is associated with the first storage region, an execution of the second request is held. In response to determining, based on the region access signal, that the second request is associated with a second storage region among the plurality of storage regions, the second request is executed.
