Toshiba has unveiled new fabricated NAND flash memories with 19nm process technology.
The new technology advance has been applied to 2-bit-per-cell 64GB chips that offer the highest density on a single chip (8GB), said the company.
Toshiba said that it will also add 3-bit-per-cell products fabricated with the 19nm process technology to its product line-up.
The 2-bit-per-cell 64Gb will be available from the end of April with mass production scheduled for the third quarter of the year (July to September 2011).
Toshiba said that the 19nm generation process technology will shrink chip size, allowing it to assemble sixteen 64GB NAND flash memory chips in one package and to deliver 128GB devices for application in smartphones and tablet PCs.
Further, the 19nm process products are also equipped with Toggle DDR2.0, which will enhance data transfer speed, said the company.
