Toshiba Electronics Europe announced the fabrication of NAND flash memories with 19nm process technology. This latest advance has already been applied to 2-bit-per-cell 64Gbit chips, which the company claims are the smallest, highest-density single chips on the market. There are also plans to add 3-bit-per-cell products fabricated with the same process.
Application of the 19nm generation process technology will further shrink chip size. As a result, 16 64Gbit NAND flash memory chips can be assembled in one package. It also allows Toshiba to deliver 128Gbyte devices for application in smartphones and tablet PCs. The 19nm process products come equipped with Toggle DDR2.0, which enhances data-transfer speed.
Samples of 2-bit-per-cell 64-gigabit will be available at the end of this month, with mass production scheduled for the third quarter (July to September 2011).
