SLC vs MLC: Which works best for high-reliability applications?

SLC vs MLC: Which works best for high-reliability applications? Charlie Cassidy, TeleCommunication Systems 7/16/2012 4:43 PM EDT As with most storage technologies, NAND flash vendors are constantly being pushed to reduce cost and increase density. One way the industry has responded is by packing more than one bit in a single flash storage cell. Known as multi-level cell (MLC) memory, this technology allows for a doubling or tripling of the data density with just a small increase in the cost and size of the overall silicon. This increase in density and decrease in cost per bit does come with its own tradeoffs, however, which have to be considered within the context of the application. Industrial, military, and avionic applications impose very different demands in terms of environmental stresses, data endurance requirements, and expected usable life compared to consumer prod...

A large amount of charge is used to represent logic ‘0,’ and a small amount of charge is used to represent logic ‘1.’ [link]
