SanDisk’s NAND flash lineup may have set a record Wednesday after the company claimed to have the world’s smallest 128-gigabit (16GB) memory chip. The 19 nanometer, three-bit-per-cell storage has a footprint of about 170mm square (0.26in square), or less than that of a penny. It’s also relatively quick for its capacity and size at 144Mbps (18MB) per second.
Chips built on the newer storage were considered ideal for smartphones, tablets, and solid-state drives for computers. Many such chips can be stacked on top of each other or side-by-side and give more reasonable capacities without having a physically larger device than they do now.
SanDisk has just recently started making 128Gb flash in large quantities on a basic level, although it has yet to say how quickly it expects the shrunken-down design to reach the market. Other companies have 128Gb chips in development, but these have been larger and usually haven’t reached into mainstream devices.
