Toshiba today announced it has begun mass producing NAND flash chips using a 24nm CMOS manufacturing process, representing the smallest geometry and highest density yet in NAND flash, the company said.
The announcement steals a bit of thunder from IM Flash -- a joint venture between Intel and Micron -- which said it would begin churning out 25nm-based NAND chips by the end of 2010.
"Toshiba leads the industry in fabricating high density, small die size NAND flash memory chips," Toshiba said in a statement. "Application of the 24nm generation process technology will further shrink chip size, allowing Toshiba to boost productivity and bring further enhancements to the high density, small sized products. The 24nm process products are also equipped with Toggle DDR, which enhances data transfer speed."
Toshiba says its latest technology has already been applied to 2 bit-per-cell 64Gb chips that are the world's smallest on a single chip (8GB), and will also add 32Gb and 3 bit-per-cell products fabricated on a 24nm process soon.
