Flash memory stores information in an array of memory cells made from floating-gate transistors. In single-level cell (SLC) devices, each cell stores only one bit of information. Multi-level cell (MLC) devices, including triple-level cell (TLC) devices, can store more than one bit per cell. The floating gate may be conductive (typically polysilicon in most kinds of flash … WebBecause it requires a high negative voltage, not a 0 or a 1, to erase a cell, they link many cells up into blocks to perform this erase operation. In that way, your programming and …
