What Is Flash Memory? Everyone talks about flash, but not too many users actually know how it works. Flash is a transistor-based silicon memory technology that can store information permanently by trapping electrons into so-called floating-gate transistors. Depending on ...  Depending on the threshold voltage of the flash cell, the transistor will either remain insulated or become conductive. SLC flash (single-level cell) has only one voltage level, while MLC (multi-level cell) flash memory is capable of storing multiple bits per cell.
