Samsung Electronics has developed a 4Gb “OneNAND” Flash memory device for use in next-gen multimedia phones. The new OneNAND memory device operates on 1.8V, reducing power consumption to nearly half of the existing 3.3V level for other types of mobile memory. It also features a micro-compact size (11x13x1.4mm), considerably smaller than mobile memory of the same capacity. It provides a sustained data read speed of 108 MByte/s, four times faster than conventional NAND Flash memory, and a write speed of 10 MByte/s, more than 60 times faster than NOR flash memory. It can store 250 sequential photographs from a 5-megapixel camera phone, or up to 120 music files.

From the Technology Graveyard
You just read about Flash. Here is what it replaced:
EPROM (UV-erasable) served 1971–2000. What ultimately replaced it?
EPROM (UV-erasable) floating-gate ROM erased by shining ultraviolet light through a quartz window, then reprogrammed on a special programmer. Its job passed to Flash — but the problem it solved, and the ideas it proved, live on in what replaced it. The standard rests here in the archive. One of 198 technologies here that opened a door and then held it for the next.
