Toshiba and SanDisk have made an announcement that they will be shifting to 15nm process for NAND memory.
This process will be replacing 19nm process starting from Toshiba’s plant in Yokkaichi, Japan. According to Toshiba, it will be using the 15nm process for 128gigabit/16GB NAND memory with two bits per cell. These chips will be used for smartphones, tablets, slim notebook PCs and enterprise products requiring high reliability, including SSD for data centers.
“We are thrilled to continue our technology leadership with the industry’s most advanced flash memory process node, enabling us to deliver the world’s smallest and most cost effective 128 gigabit chips,” said Dr. Siva Sivaram, senior vice president, memory technology, SanDisk. “We are delighted that these new chips will allow us to further differentiate and expand our portfolio of NAND flash solutions.”
SanDisk said that their company is utilizing its 15nm process called as ‘1Z-nm node’. The company wants to make 128bit NAND modules with two bits per cell and three bits per cell by second half of 2014. SanDisk’s spokesperson said,”Our 15-nm technology will be utilized across its broad range of solutions, from removable cards to enterprise SSDs.”
It was added that shifting to 15nm process helped SanDisk to make cost effective chips in comparison with the previous process called as 1Y-nm nodes. The flash storage maker will be using All-Bit-Lane architecture with proprietary programming algorithms and multi-level data storage management schemes.
