Toshiba Corp. on Tuesday started mass production of NAND flash memories fabricated with 24nm process technology. The new manufacturing process will be used to make low-cost 64Gb flash chips.
This latest technology advance has already been applied to 2bit-per-cell (2bpc) 64Gb chips that are the world's smallest and offer the highest density on a single chip (8GB), 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.
By accelerating process migration in NAND flash memory, Toshiba aims to reinforce and extend its leadership in the NAND flash memory market.
