Charge trapping flash is similar in manufacture to floating gate flash with certain exceptions that serve to simplify manufacturing. Both floating gate flash and charge trapping flash use a stacked gate structure in which a floating gate or charge trapping layer lies immediately above the channel, and below a control gate. The floating gate or charge trapping layer is insulated from the channel by a tunnel oxide layer and fr… WebOne of the transistors is known as the floating gate and the other as the control gate. The floating gate's only link to the row ( wordline) is through the control gate. As long as this link is in place, the cell has a value of 1. To change the value to 0 requires a curious process called Fowler-Nordheim tunneling.
WebAn over-erased cell creates a leakage current path between the drain and floating gate, which can result in read failures. To combat this effect, stacked gate Flash requires multiple erase pulses, soft-programming and erase verification cycles to ensure a tight threshold voltage window of the Flash cell.
