Floating gate nand cell
WebMar 11, 2024 · Until recently most NAND flash relied on floating gate technologies, in which the electrons are trapped between two oxide layers in a region called the floating gate. The bottom oxide layer is thin enough for electrons to pass through when voltage is applied to the underlying substrate. WebThese defects change the potential energy between floating gate and substrate and reduces the program/erase efficiency during operations. As trapped charges accumulate in the tunneling oxide layer, the programming characteristics may also shift. ...
