Abstract
A memory cell for storing one or more bits of information has a control gate, a source terminal and a drain terminal. A semiconductor substrate is located between the source and drain terminals, and a floating gate is disposed between the control gate and the semiconductor substrate. The floating gate is electrically isolated from the control gate by a charge trapping barrier, and is electrically isolated from the semiconductor substrate by a charge blocking barrier. At least one of the charge trapping barrier and the charge blocking barrier contains a III-V semiconductor material. The charge trapping barrier is adapted to enable the selective passage of charge carriers between the control gate and the floating gate, in use, to modify the one or more bits of information stored by the memory cell.
