SanDisk Creates 19nm-Based 64 Gb NAND Flash Memory

To some, it might feel that the 20nm manufacturing process started to be used just yesterday, but it looks like an even more advanced node has been developed, courtesy of SanDisk.

NAND Flash memory became important when it started to be used in mobile devices, like phones and handsets.

Still, the real push came when the solid state drive was invented, showing that there was a faster and more reliable alternative to the HDD.

Granted, cost issues have always existed, but the gap keeps narrowing as better manufacturing processes are employed.

The most advanced one is now that of 19nm, which SanDisk proudly announced after it used it to create a 64-gigabit (Gb), X2 (2-bits-per-cell) based monolithic chip.

“We are excited to introduce the world’s smallest and lowest-cost NAND flash chips based on industry-leading 19nm process technology in our ongoing collaboration with our manufacturing partner Toshiba,” said Yoram Cedar, executive vice president and chief technology officer, SanDisk.

“Products based on this technology are designed to enable new applications, form factors and consumer experience that will continue to drive the flash industry to new heights.”

Being the most sophisticated flash memory to date, the chip has advanced cell design and 'process innovations.'

The new chip is made with the All-Bit-Line (ABL) architecture which, thanks to proprietary programming algorithms and 'multi-level data storage management schemes' help create MLC NAND memory with no reliability or performance sacrifices.

Currently, only samples of the 19nm 64 Gb (8 GB) X2 device exist and they haven't yet started shipping to product makers, although this step should be taken before the quarter is out. By then, there should also be 3-bits-per-cell (X3) 19nm-based product available.

Mobile phones, tablets computers and pretty much any consumer electronics or industrial device that doesn't use HDDs will be able to benefit from the new technology.
