Abstract
A field effect transistor storage device for use in programmable read-only memories of the type employing a floating gate and a control gate overlying and aligned with the floating gate. An erase gate is provided adjacent at least one edge of the floating gate for removing charge stored on the floating gate. A method of electrically erasing the storage device includes holding the control gate at a fixed potential to thereby hold the floating gate at a substantially fixed potential while a relatively low voltage is applied to the erase gate to remove charge stored on the floating gate.
