Replacing second generation 19nm process technology (the company's former flagship process), Toshiba has developed what it claims to be the world’s first 15nm process technology. The chips achieve the same write speed as chips formed with second generation 19nm process technology, but boost the data transfer rate to 533Mb/s, 1.3 times faster, by employing a high speed interface.

Toshiba has achieved the world’s smallest class chip size with the 15nm process plus improved peripheral circuitry technology. The 15nm process technology will apply to 2-bit-per-cell 128Gb (16GB) NAND flash memories.

Toshiba is now applying the 15nm process technology 3-bit-per-cell chips, and aims to start mass production in the first quarter of this fiscal year, to June 2014. The company will develop controllers for embedded NAND flash memory in parallel and introduce 3-bit-per-cell products for smartphones and tablets, and will subsequently extend application to notebook PCs by developing a controller compliant with solid state drives (SSD).

Toshiba continues to closely follow its process technology development roadmap and will strengthen product competitiveness and performance by applying leading-edge process to production. Looking to the future, Toshiba will reinforce its market leadership by promoting product innovation and development and ensuring that it is able to respond to a wide variety of clients' product needs, including smartphones, tablets, slim notebook PCs and enterprise products requiring high reliability, including SSD for data centres.
