STORAGE CONTROLLERS AND STORAGE SYSTEMS

A storage controller includes a learning pattern processor and a storage processor. The learning pattern processor estimates request prediction data to be requested by a host per epoch to generate estimated result values of the request prediction data. The storage processor reads the request prediction data from a storage memory to store the request prediction data in a buffer memory based on the estimated result values before the host issues a read request for the request prediction data. An operation speed of the buffer memory is higher than an operation speed of the storage memory.
