IMFT can make 128GB NAND in a single fingertip-sized package
Production could quadruple, but demand is still high
Intel Micron Flash Technologies, commonly known as IMFT, is a major manufacturer of the NAND flash memory used in Solid State Drives, tablets, smartphones, and other devices. Most of the company's production is currently on the
, but it is currently transitioning to a 20nm process. IMFT first began test production of the new 64Gb chips in April, but has now moved into full production at its fab in Lehi, Utah.
The new 64Gb chips measure 118mm
and use High-k Metal Gate (HKMG) technology to reduce gate leakage. A planar cell structure is also used to produce a more symmetrical die, allowing for easier packaging than conventional floating gate cells. This allows for identical 3-5K write cycling as found in the 25nm MLC NAND.
IMFT is currently testing a larger 128Gb chip for mass production next year. It will meet the ONFI 3.0 specification and achieve speeds of up to 333 MT/s. Page sizes will double from 8KB to 16KB. The new design will enable 16GB of storage in a single chip, and 128GB in a typical eight die package. SSDs of up to 2 terabytes will be available using these new chips.
is planning on the introduction of a new generation of SSDs using 20nm NAND within 2 to 3 quarters, according to a source within the company. Seagate also uses NAND from IMFT in its
Momentus XT hybrid drives
, and will most likely use a 16GB MLC chip in its next generation.
Intel Micron Flash Singapore (IMFS) is currently using the 25nm process as well, and will transition to 20nm in late 2012. The new 128Gb chips will almost quadruple the amount of NAND produced by IMFT. This will likely
lower production costs
, leading to lower prices for consumers. However, all of this massive supply will be tempered by strong consumer demand as more tablets, SSDs, and hybrid drives hit the market in 2012.

MLC in Seagate XT ?

If they start to use MLC they will have to be sure to have good wear leveling system.

I'm going to touch on this point during my presentation today at Seagate's Solid State Hybrid Drive webinar. Register for a chance to win a next-generation laptop!
