Abstract: A nonvolatile memory device includes a memory cell array to store an original setting data, a page buffer circuit connected to the memory cell array through a plurality of bit-lines, a secure buffer and a control circuit. The secure buffer includes an access control circuit and a plurality registers with restricted access, and the plurality registers store the original setting data that is dumped-down from the memory cell array through the page buffer circuit in an initialization sequence. The control circuit controls the page buffer circuit and the secure buffer. The plurality registers include a first register and second registers. The access control circuit, in response to the first register being accessed, accesses at least a portion of the second registers concurrently with accessing the first register.

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.
