Abstract:
A memory storage device comprising:a storage medium having a plurality of coverage areas, each of said coverage areas having a storage area associated therewith, each of said storage areas being configurable in one of a plurality of structural states to represent information stored in said storage area; a plurality of electron beam emitters configured to electrically communicate with said storage medium, said storage medium and said plurality of emitters being configured to move relative to each other such that each of said emitters is capable of providing a beam of electrons to a respective one of said coverage areas of said storage medium; a first current source configured to enable the at least one of said emitters to provide a beam of electrons to a respective one of said coverage areas; and a shield disposed in proximity to said plurality of emitters, said shield being configured to reduce an influence of a magnetic field such that a tendency of an electron emitted from one of said emitters to be displaced from an intended trajectory is reduced.
