Toshiba launches 19nm process NAND flash memory

Toshiba has disclosed it is now capable of producing NAND flash chips using 19nm process technology. The claim was made following Intel and Micron Technology's joint announcement recently that the pair has developed a 20nm process technology for manufacturing NAND chips.
Toshiba announced it has fabricated NAND flash chips on 19nm process technology, the finest level yet achieved. This latest technology advance has already been applied to 2-bit-per-cell 64Gb chips enabling 8GB on a single chip.
Toshiba said it will also add 3-bit-per-cell products fabricated with the 19nm process technology to its product lineup.
Samples of 2-bit-per-cell 64Gb chips will be available from the end of April with mass production scheduled for the third quarter of 2011, Toshiba said.
Application of the 19nm generation process technology will further shrink chip sizes, allowing Toshiba to assemble 16 64Gb NAND chips in one package and to deliver 128GB devices for smartphones and tablet PCs, the company indicated. The 19nm process products are also equipped with Toggle DDR2.0, which enhances data transfer speed.
