Abstract: The scale of the devices in a diode array storage device, and their cost, are reduced by changing the semiconductor based diodes in the storage array to cold cathode, field emitter based devices. The field emitters and a field emitter array may be fabricated utilizing a topography-based lithographic technique.

Abstract: A ballistic memory cell structure employing ballistic transistor technology for switching between a read state and a store state is disclosed. The memory cell structure includes substrate structures forming a side wall and a main chamber for defining a linear ballistic channel between the two. The main chamber is formed to include a deflection channel with deflective surfaces to deflect an electron emitted from an electron source into the memory cell structure. Deflection controllers are coupled to the substrate structures for generating biasing fields that adjust the trajectory of electrons flowing through the linear ballistic channel and the deflection channel. Logic output terminals are positioned beyond channel exits for registering exiting electrons and determining a read or store state.
