SLC NAND Flash in Embedded Systems

There are two primary types of NAND flash technology: Single-level cell and multilevel cell. Multi-level cell was developed more recently, to achieve higher bit density, so that a much higher capacity flash chip could be created for a given die size. MLC might allow you to save cost for flash chips and save board space by reducing the number of chips you need. But before you rush to design MLC into your embedded system, there are a few things you should know, and other options you can consider.
