Abstract
A disk controller system includes a microprocessor, a hard disk controller, a disk channel path, a host communications path, and an interface coupled to each of the microprocessor, hard disk controller, disk channel path and host communications path. A unified non-volatile memory is coupled to the interface that has a plurality of memory spaces. A memory space is allocated for each of the microprocessor, hard disk controller, disk channel path and host communications path. Each memory space is separated from another memory space by a programmable memory space boundary. The microprocessor, hard disk controller and the unified memory are all fabricated on a single substrate.
