What is cMLC Flash?

cMLC - Commercial Multilevel Cell NAND FlashSome recent news mentioned cMLC flash, which is short for “consumer MLC.”  This term is used to differentiate between the cheapest available product, mainstream MLC, and products that are aimed at the computing segment, and thus carry higher price tags.

There are several of these higher-end products.   Some have longer endurance, like eMLC and SLC flash.  Some have faster interfaces, like ONFi and Toggle Mode.  Then there are the combinations of these: a fast interface with enhanced reliability.

There are disadvantages to these.  The consumer market Continue reading

Micron, Intel, Introduce 128Gb NAND Chip

IMFT 20nm NAND Flash DieMicron Technology and Intel announced today (6 December, 2011) that the two companies are sampling a 128 gigabit (that’s 16 gigabytes) NAND flash chip manufactured by the company’s IMFT joint venture.

This is a doubling of the capacity of the 64Gb chip the companies announced in April, but they assure us that the size of the die hasn’t doubled, and the accompanying photo supports this.  Intel tells us that the die will fit into standard BGA and TSOP packages. Continue reading
