SanDisk reveals 128GB NAND flash memory chip

The world's smallest 128GB NAND memory flash chip has been unveiled by SanDisk.

SanDisk has proudly announced the creation of the world's smallest 128GB NAND Flash memory chip.

The device consists of a single silicon die measuring 170mm squared, or a quarter of an inch squared in old money.

SanDisk says that by shrinking the size of NAND flash memory cards for use in solid-state drives and tablets makes for smaller yet more powerful computing technology.

This in turn enables further advancements in the performance of such devices while keeping costs low.

The NAND flash memory chip was created using "industry-leading" 19 nanometer process technology, which involves circuit lines so small that around 3,000 could fit across the width of a human hair.

Added to this is SanDisk's three-bit per cell technology that allows it to build NAND flash memory products that can read three bits of information per memory cell.

"Building a 128GB NAND flash memory chip with this level of complexity is an incredible achievement," said Mehrdad Mofidi, vice president of memory design at SanDisk.

"This innovation allows SanDisk to continue to be a leader in helping our customers deliver smaller, more powerful products capable of doing more at lower cost."

In terms of performance, the new chip delivers an industry-leading X3 write performance of 18MB per second. SanDisk believes that this will allow X3 technology top be expanded into other product lines.

The announcement comes shortly after SanDisk announced the introduction of a new retail SSD, the Extreme.

Said to be up to ten times faster than a 7,200 RPM hard disk drive, the SanDisk Extreme SSD can apparently boot-up your PC in less than 16 seconds, and shut it down even quicker.

"Computer wait times are becoming a thing of the past thanks to SSDs," said Kent Perry, director, product marketing, SanDisk.ADNFCR-1220-ID-801301362-ADNFCR
