Samsung is showing its muscle in the flash memory business by announcing that it has managed to produce the first NAND chips based on the 20nm manufacturing process. These chips are based on multi-level cell (MLC) NAND technology, and the 32GB chips are designed to be used in SD memory cards and devices that need embedded memory. Samsung is already shipping SD cards based on this technology to its customers, and is planning to expand production later in 2010. The benefits of this achievement is that Samsung should be able to manufacture greater yields of working chips at a cheaper cost, and we’ll also get the added benefit of improved performance. It seems that SD cards based on the 20nm chips will be available in capacities ranging from 4GB to 64GB.
