Intel and Micron's Joint Venture to Create World's First 128Gb 20nm MLC NAND

At the beginning of 2011, Intel and Micron's joint manufacturing venture NAND (IMFT) announced that they had produced a 64Gb (8GB) MLC NAND on a 20nm process. Many IMFT NAND used in SSDs are made by using a 25nm process.

The reason behind using this process is that it reduces die size which eventually reduces the overall cost in manufacturing.

Intel and Micron have recently started a second generation 20nm part at a 128Gb with 16GB capacity, which also signifies the continuation of their successful partnership.

The 128Gb 20nm MLC NAND features ONFi 3 interface rather than the ONFI 2.x which was used earlier in the 64Gb and older 25nm parts, as reported by AnandTech.

What makes the new ONFI 3 special is that it enhances interface bandwidth from a maximum of 200MT/s (IMFT 25nm was limited to 166MT/s) to around 333MT/s.

All in all we can expect high powered performance from this new joint effort by Intel and Micron. Joint ventures, when successful, can provide a platform for innovation and imagination that allows engineers and others to experiment and discover new ways to design and develop technology and equipment.
