Resistive random access memory (RRAM), could be a better kind of nonvolatile memory. Nonvolatile memory is the basis for flash memory in thumb drives, but flash technology has reached its size and performance limits. For several years, the industry has been hunting for a replacement. RRAM could surpass flash in many key respects: It is potentially faster and less energy-intensive. It also could pack 1TB into a postage stamp. But RRAM has yet to be broadly commercialized because of technical hurdles.
