An EPROM cell with a magnesium electronic injector

By using Mg as the tunnelling electrode for an EPROM cell, it is shown in a control experiment that the tunnelling current is much enhanced while the tunnelling field is much reduced after a sintering procedure in which Mg reacts with the SiO/sub 2/ dielectric. Potentially, this may lead to faster programming, lower programming voltages and better programming endurance. An experimental EPROM cell has been made and has demonstrated programmability.
