Description
Park and co-authors stack memory into a computer in this 2026 electronics study, fabricating a two-deck resistive memory array whose layers share a middle electrode. Each memory cell can run as its lower layer alone, its upper layer alone, or both layers wired in series, giving one physical footprint three operating personalities selectable by voltage.
The fabricated array measures 2 by 16 by 16 cells. A pulse-with-verify programming scheme coaxed all modes into stable multilevel storage. The storage ran at 6-bit resolution, with 64 distinct conductance states. It was retained beyond ten thousand seconds. It also survived over a hundred switching cycles in testing. A neural network evaluation on the CIFAR-10 image task scored about 93.4 percent inference accuracy in every mode. The series mode additionally performed logic inside memory and generated near-ideal randomness for hardware security fingerprints.
