Toshiba launches 19nm process NAND flash memory for 128Gbytes in a single package

By Nick Flaherty 

Despite production problems in the wake of the Japan earthquake and power shortages, Toshiba Electronics Europe has made NAND flash memories with 19nm process technology, the finest level yet achieved. This latest technology advance has already been applied to 2-bit-per-cell 64-gigabit (Gb) and Toshiba says it will also add 3-bit-per-cell products fabricated with the 19nm process technology to its product line-up. This will make solid state disk drives significantly more cost effective.
Samples of 2-bit-per-cell 64-gigabit will be available from the end of this month with mass production scheduled for the third quarter of the year (July to September 2011).
The 19nm process technology will further shrink chip size, allowing Toshiba to assemble sixteen 64Gbit NAND flash memory chips in one package and to deliver 128GB devices for application in smartphones and tablet PCs. The 19nm process products are also equipped with Toggle DDR2.0, which enhances data transfer speed.
As the market for mobile equipment, such as smartphones, tablet PCs, and SSDs (solid state drives) expands, demand for smaller, higher density memory products grows. By accelerating process migration in NAND flash memory, Toshiba aims to reinforce and extend its leadership in the NAND flash memory market.
