Warning: Indepth engineering speak. Interesting look into the technology.
The technical and manufacturing prowess of Intel Micron Flash Technologies (IMFT) is proven once again by the introduction of their latest 25-nm 8-GB (64 Gb), 2-bit/cell MLC (multi-level cell) NAND flash. While most pundits have speculated that NAND has hit the wall, IMFT continued their aggressive path of NAND scaling and may even get one more node at 18 nm. On the scaling front, it's clear that IMFT is following 0.7x scaling every 12-15 months, which translates to almost 0.97x scaling compared with the logic technology time scale.
