Toshiba claims it can now make flash memory chips using the 19-nanometer process. It has said that the process will be applied to 2-bit-per-cell 64GB chips. The company will also add in 3-bit-per-cell products fabricated with the 19nm process to its offerings.
It’ll allow Toshiba to develop sixteen 64GB NAND flash memory chips in one package, it says. Furthermore it will be able to push forward 128GB devices as well as adding Toggle DDR2.0, which will enhance data transfer speed.
The company said that it will begin churning out samples at the end of this month and plans to start mass production in the July-September quarter.
Meanwhile Sandisk has launched a 64-gigabit (Gb), 2-bits-per-cell (X2) based monolithic chip made on 19-nanometer (nm).
SanDisk said it will sample its 19nm 64Gb X2 device this quarter and expects to begin high-volume production in the second half of 2011. Like its old mate Toshiba, the company has said that it will also be adding 3-bits-per-cell (X3) products fabricated with the 19nm process to its product lineup.
The 32 gigabit MLC NAND is claimed to have a 50 percent greater productivity level than 30 nanometer MLC NAND.
