System and method for configuring and controlling non-volatile cache

A host system comprising:

• an interface configured to communicate with a memory device, the memory device include a non-volatile cache;
• and
• processor circuitry in communication with the interface, the processor circuitry including:
• a cache configuration module configured to generate a configuration command, the configuration command indicative to the memory device to configure the non-volatile cache;
• a cache control module configured to generate a control command, the control command indicative to the memory device to control operation of the non-volatile cache;
• and
• a command transmission module configured to transmit, via the interface, the configuration command and the control command to the memory device.

A memory device comprising:

• an interface configured to communicate with a host device;
• a non-volatile memory;
• and
• processor circuitry in communication with the interface and the non-volatile memory, the processor circuitry including:
• a non-volatile size command module configured to receive a size command via the interface from the host device, the size command indicative of a size of the non-volatile cache;
• and
• a non-volatile cache allocation module configured to, in response to receipt of the size command, allocate one or more sections of the non-volatile memory to the non-volatile cache, with the one or more sections of the non-volatile memory not being equal to the size as indicated in the size command.
