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.

Abstract: Disclosed is a storage device configured to receive a read command or a write command from a host device, the storage device comprising, a non-volatile memory device configured to store data, and a storage controller configured to operate at least one virtual machine to control the non-volatile memory device, store a workload threshold of the at least one virtual machine according to settings received from the host device, and send an asynchronous event interrupt to the host device based on the workload threshold, wherein the storage controller is further configured to, store the workload threshold for the at least one virtual machine, monitor read commands or write commands received from the host device to count and update a workload, and determine whether to send the asynchronous event interrupt based on the workload and the workload threshold.
