Samsung Electronics has announced it has begun volume production of a 128-Gbit, 3-bit Multi-Level Cell (MLC) NAND memory using 1x-nm class process technology. Samsung defines 1x-nm class to be somewhere between 10-nm and 19-nm.
Samsung claims its chip has the highest physical density and the highest performance as it can move data at 400-Mbits per second using a toggle DDR 2.0 interface. Micron Technology Inc. recently announced a 128-Gbit 3-bit MLC NAND flash memory made using a 20-nm manufacturing process (see Micron launches dense 128-Gbit NAND flash)
“By introducing next-generation memory storage products like the 128Gb NAND chip, Samsung is extremely well situated to meet growing global customer needs,” said Young-Hyun Jun, executive vice president, memory sales & marketing, Device Solutions Division, Samsung Electronics. “The new chip is a critical product in the evolution of NAND flash, one whose timely production will enable us to increase our competitiveness in the high density memory storage market.”
Samsung started production of 10nm-class 64Gb MLC NAND flash memory in November last year, and in less than five months, has added the new 128Gb NAND flash to its wide range of high-density memory storage offerings. The new 128Gb chip also extends Samsung’s 3-bit NAND memory line-up along with the 20nm-class 64Gb 3-bit NAND flash chip that Samsung introduced in 2010. Further, the new 128Gb 3-bit MLC NAND chip offers more than twice the productivity of a 20nm-class 64Gb MLC NAND chip.
No details of the read or write performance, or the cycling endurance were provided by Samsung in a press release nor did the company provide a part number.
Samsung said it would use the 128-Gbit NAND flash memory to expand its supply of 128-Gbyte memory cards, which can store as many as sixteen 8GB full HD video files, and to increase its production of solid-state drives with densities above 500-Gbyte for wider adoption of SSDs in computer systems, while leading the transition of main storage drives in the notebook market from hard disk drives (HDDs) to SSDs.
Demand for high-performance 3-bit MLC NAND flash and 128Gb high storage capacities has been rapidly increasing, driving the adoption of SSDs with more than 250GB data storage, led by the Samsung SSD 840 Series.
