Floating gate vs replacement gate
WebMOSFETs with floating gates (known as floating gate MOSFETs, or FGMOS) are used to create an array of memory cells in flash memory chips. In this structure, the gate is electrically isolated from the rest of the transistor, while secondary terminals are formed above the gate structure. This allows charge accumulated on the gate to persist for ... WebMay 23, 2024 · The biggest difference is that Intel/Micron picked floating gate as the storage element while Samsung and, apparently, everyone else chose a charge trap technology which is an easier technology...
