Abstract: According to one embodiment, a key search circuit includes a hit determination circuit that determines whether a key search request hits a content stored in a search result buffer, and an update determination circuit that determines whether to update the content stored in the search result buffer. When the hit determination circuit determines that the key search request hits the search result buffer, the key search circuit outputs the search result stored in the search result buffer to an encryption/decryption circuit. When the update determination circuit determines to update the search result buffer, the key search circuit updates the content stored in the search result buffer with the key search request and a search result obtained from a range table.

Abstract: According to one embodiment, a read controller reads data and metadata from a nonvolatile memory. The read controller includes a reader, a read mode changer and a first data processor. The reader reads first data and first metadata from the nonvolatile memory. The read mode changer determines whether to execute sequential processing for the first data based on the first metadata. When the read mode changer determines that the sequential processing is to be executed, the first data processor stores information necessary for the sequential processing, executes the sequential processing for the first data, and generates second metadata including a result of the sequential processing. The read controller outputs the first data, and the first metadata or the second metadata.
