Researchers Build Computer-on-a-Chip Prototype

Chip computer

Stanford researchers led an international team of engineers that figured out how to pack many functions of a computer onto a single chip, including processing circuits, memory storage, and a power supply. The prototype’s data processing and memory circuits use less than a tenth as much electricity as comparable electronic devices, yet still perform many advanced computing feats.

The prototype is built around data storage technology called resistive random-access memory (RRAM), which can pack more data into less space than any other form of memory and retains data when the chip hibernates—an energy-saving tactic built into the chip. It is also energy-efficient, so as to not overtax power supplies.

RRAM can also be built atop a processing circuit to combine data storage and computation into a single chip. This adds more energy efficiency and speeds processing.
