Abstract:

Semiconductor memory components provide opportunities for new computer memory structures due to two advantages they offer over core memories 1 Logic can be integrated into the memory structures, and 2 small blocks of memory can be accessed independently for improved access flexibility. This research proposes using these properties to achieve a more efficient implementation of a virtual memory system. The proposed system uses novel semiconductor memory chips to integrate the address-mapping function and the data-multiplexing function into the memory circuits, with consequent saving of external overhead circuitry. This proposed system is compared in detail with a conventional implementation of a virtual memory system, showing cost and performance figures for a variety of system configurations. The proposed system is shown to give superior results in smaller memories or in high-performance memories.
