August 16, 2012 -- NAND flash memory has been on the market for decades and many of the electronic products we use on a daily basis feature some form of NAND, from wireless phones to automobiles, but the function this memory serves can be vastly different. This difference in function has caused a divergence in the evolution of NAND flash memory, leading to two distinct memory product categories: commodity and embedded NAND.
Commodity NAND flash memory is commonly used in consumer devices; these devices are price sensitive and require mass storage for music, videos, books, photos, games and other user data. Over time, the demand for storage has increased, but the sensitivity towards price has stayed the same. As a result, there is a never-ending urgency for commodity NAND suppliers to continuously reduce cost.
Devices in the embedded market, such as set-top boxes, automobiles, industrial meters, sensors and GPS navigation systems, do not follow the same storage/ cost cycle as those within the commodity NAND flash market. These devices require NAND flash memory that focuses more on reliability than large storage space. The important function of embedded NAND flash memory is to provide predictable performance and long-term product support. Embedded NAND suppliers are held to a higher standard than commodity NAND suppliers, who are driven by the agenda of driving down cost.
