Abstract
Systems, apparatus, and computer-implemented methods are provided for the hybridization of cache memory utilizing both magnetic and solid-state memory media. A solid-state cache controller apparatus can be coupled to a host computing system to maximize efficiency of the system in a manner that is transparent to the high-level applications using the system. The apparatus includes an associative memory component and a solid-state cache control component. Solid-state memory is configured to store data blocks of host read operations. If a host-read operation is requested, the controller communicates with a solid-state cache memory controller to determine whether a tag array data structure indicates a cached copy of the requested data block is available in solid-state memory.
