Abstract: A non-volatile memory device includes a semiconductor substrate and a pair of buried bitlines within the substrate. A scaled down dielectric stack is formed over the substrate. The scaled down dielectric stack includes a scaled down top dielectric layer, a scaled down charge trapping dielectric layer and a bottom dielectric layer. A wordline is formed over the dielectric stack. The memory device is operative to be programmed using a reduced wordline operating voltage of less than about +8 Volts, and to be erased using a reduced wordline operating voltage of less than about ?6 Volts.

Abstract: A method of fabricating a dual bit dielectric memory cell structure on a silicon substrate includes implanting buried bit lines within the substrate and fabricating a layered island on the surface of the substrate between the buried bit lines. The island has a perimeter defining a gate region, and comprises a tunnel dielectric layer on the surface of the silicon on insulator wafer, an isolation barrier dielectric layer on the surface of the tunnel dielectric layer, a top dielectric layer on the surface of the isolation barrier dielectric layer, and a polysilicon gate on the surface of the top dielectric layer. A portion of the isolation barrier dielectric layer is removed to form an undercut region within the gate region and a charge trapping material is deposited within the undercut region.

Abstract: An electrically actuated aircraft brake and method characterized by the use actuator modules which can be easily and quickly replaced as a unit. Quick and easy replacement of the actuator modules can be effected without disassembly of the overall brake and wheel assembly. Accordingly, brake manufacturing, repair costs, overhaul, parts stocking and maintenance costs and requirements are minimized and/or greatly simplified compared to integrated brake designs used in the prior art. Also, a malfunctioning actuator module on an aircraft can be replaced and preferably quickly enough to allow the aircraft to remain in scheduled service and/or with a minimum of downtime.
