A Stanford University-led engineering team has developed a prototype computer-on-a-chip, whose data processing and memory circuits consume less than a tenth as much electricity as any comparable electronic device.
In collaboration with researchers at the CEA-LETI institute in France, the Stanford team used resistive random access memory (RRAM) as a key element of the new chip.
RRAM features storage density that can embed more data within less space than other forms of memory, while its energy efficiency does not strain limited power supplies; it also can retain data during chip hibernation.
Engineers also can build RRAM directly atop a processing circuit to integrate data storage and computation within a single chip, and the CEA-LETI cohort grafted the RRAM onto a silicon processor.
The Stanford team boosted RRAM storage capacity, and developed an algorithm to lengthen endurance, so the prototype should be capable of operating for a decade.
