Abstract
A memory system includes a nonvolatile memory and a memory controller including a bus, a cache memory, a direct memory access controller, a first search circuit, a second search circuit, and a transfer control circuit. The direct memory access controller transfers cache target data stored in the nonvolatile memory to the cache memory. The second search circuit searches the cache target data that is being transferred. The transfer control circuit assigns, in response to the second search circuit detecting a search hit, to the transfer control circuit and the second search circuit, a bus right which has been assigned at least to the cache memory for the transfer of the cache target data to the cache memory, and obtains, by using the assigned bus right, a search result from the second search circuit via the bus.
