Abstract
A storage system includes a storage device and a host device. The storage device includes a nonvolatile memory device having a first size and a first volatile memory device having a second size smaller than the first size and configured to operate as a cache memory with respect to the nonvolatile memory device. The first volatile memory device is configured to allow a first bus portion access to cache data stored in the first volatile memory device. The host device is configured to generate a cache table corresponding to information in the cache data stored in the first volatile memory device and configured to read the cache data stored in the first volatile memory device via the first bus portion based on the cache table.
