CABLE BANDWIDTH EXTENDER

A cable for use between a host and an external memory. The cable has a first and second ends and two or more electrically conductive conductors, surrounded by an insulator, extending from the first to the second end. At the first end is a first cable connector that is electrically connected to the conductors and physically connected to the insulator. The first cable connector connects to an external memory. A second cable connector, at the second end, is electrically connected to the conductors and physically connected to the insulator. The second cable connector connects to a host. A final level cache (FLC) system, in the second cable connector, comprises a connector memory with associated controller configured to store data, and a FLC controller with memory. The FLC controller stores memory addresses that correspond to data stored in the connector memory and operates the connector memory as a cache memory.
