High-Speed Plated-Wire Memory System

The plated-wire memory, combined with functional circuit integration, is a strong contender for economic, high-speed, large-capacity memory systems. Important attributes of the plated-wire memory are high-speed DRO and NDRO capability, low digit WRITE current, high output sense signal and low word-to-digit line crosspoint capacitance. Design and operational results for a 1024-word by 80-bit store model are reported in detail. Utilizing a transformerless diode matrix for high-speed word selection, an access time of 75 ns and a READ-WRITE cycle time of 150 ns have been realized.
