PROBLEM TO BE SOLVED: To provide a storage system that includes: a cache memory that does not need replacement of a power storage device; a cache memory that consumes less power; or a cache memory that does not have a limit on the number of rewrite times.SOLUTION: An array controller for storing externally input data in any of a plurality of storage devices; or a storage system that includes the array controller includes: a processor that specifies which of the plurality of storage devices stores the data; and a cache memory that stores the data and outputs the data to any of the plurality of storage devices. The cache memory includes a storage circuit that uses a transistor having an oxide semiconductor layer. |
