Samsung touts 20nm NAND for smartphones

Sasmsung has kicked off production of its 20 nanometer (nm) class 32GB NAND chips.

The chips – which are slated to be used in Secure Digital (SD) memory cards – will help expand the company’s lineup for smart phones, high-end IT apps and memory cards.

“Samsung’s 20nm-class MLC NAND has a 50 percent higher productivity level than 30nm-class MLC NAND,” explained senior Samsung executive Soo-In Cho.

“The write performance of a 20nm-class-based, eight gigabyte (GB) and higher density, SD card is 30 percent faster than the 30nm-class NAND and it delivers a speed-class rating of 10 (read speed of 20MB/s, write speed of 10MB/s).”

According to Cho, Samsung first began producing 32Gb NAND with 30nm-class process technology in March 2009 and is currently shipping SD card samples to customers that were manufactured with 20nm-class 32Gb NAND.

He added that memory cards based on the 20nm-class will be available in 4GB-64GB densities.
