Structures and methods for DEAPROM memory with low tunnel barrier intergate insulators are provided. The DEAPROM memory includes a first source/drain region and a second source/drain region separated by a channel region in a substrate. A floating gate opposes the channel region and is separated therefrom by a gate oxide. A control gate opposes the floating gate. The control gate is separated from the floating gate by a low tunnel barrier intergate insulator having a tunnel barrier of less than 1.5 eV. The low tunnel barrier intergate insulator includes a metal oxide insulator selected from the group consisting of NiO, Al₂O₃, Ta₂O₅, TiO₂, ZrO₂, Nb₂O₅, Y₂O₃, Gd₂O₃, SrBi₂Ta₂O₃, SrTiO₃, PbTiO₃, and PbZrO₃. The floating gate includes a polysilicon floating gate having a metal layer formed thereon in contact with the low tunnel barrier intergate insulator. And, the control gate includes a polysilicon control gate having a metal layer formed thereon in contact with the low tunnel barrier intergate insulator.
