Non-volatile memory is described. The non-volatile memory includes a
substrate having a source region, a drain region and a channel region.
The channel region separates the source region and the drain region. An
electrically insulating layer is adjacent to the source region, drain
region and channel region. A floating gate electrode is adjacent to the
electrically insulating layer. The electrically insulating layer
separates the floating gate electrode from the channel region. The
floating gate electrode has a floating gate major surface. A control gate
electrode has a control gate major surface and the control gate major
surface opposes the floating gate major surface. A vacuum layer or gas
layer at least partially separates the control gate major surface from
the floating gate major surface.
