Flash memory hot carrier injection
WebMay 1, 2006 · Program disturbs in NOR-type Flash arrays significantly degrade the tunnel oxide by hot-hole injection (HHI) induced by band-to-band tunneling at the drain overlap. This paper provides a... WebFlash memory works by adding (charging) or removing (discharging) electrons to and from a floating gate. A bit's 0 or 1 state depends upon whether or not the floating gate is charged or uncharged. When electrons are present on the floating gate, current can't flow through the transistor and the bit state is 0.
