Fusion-io recently announced SMLC flash memory. What is SMLC? To understand how Fusion-io coined this acronym (and it is all theirs), you need to first become familiar with two more--SLC for Single Level Cell and MLC for Multi Level Cell. Both refer to types of NAND flash memory, and both are hot items right now, but for different reasons.
