Toshiba announced that it today started mass production of
NAND flash memories fabricated with 24nm process technology.
This latest technology advance has already been applied to
2bit-per-cell 64-gigabit (Gb) chips that are the world's
smallest and offer the highest density on a single chip (8
gigabytes (GB)), and which are available from today. Toshiba
will also add 32Gb and 3bit per cell products fabricated with
the 24nm process technology to its product line-up.
Toshiba leads the industry in fabricating high density, small
die size NAND flash memory chips. Application of the 24nm
generation process technology will further shrink chip size,
allowing Toshiba to boost productivity and bring further
enhancements to high density, small sized products. The 24nm
process products are also equipped with Toggle DDR, which
enhances data transfer speed.
As more mobile equipment, such as smartphones, digital video
cameras and tablet PCs, provide support for recording high
resolution pictures and video and editing and processing large
volumes of data, demand is growing for smaller, higher density,
memory products. By accelerating process migration in NAND
flash memory, Toshiba aims to reinforce and extend its
leadership in the NAND flash memory market.
