DEFINITION
Classification: 365/118
Electron beam:
(under subclass 106) Subject matter wherein the memory material has its state changed by radiant energy which is an electron beam.
(1) Note. This subclass will accept cathode-ray tube (CRT) storage with random access means.
SEE OR SEARCH THIS CLASS, SUBCLASS:
128, for memories using electron beams for information masking, e.g., CRT with masking means.
217, for read/write circuits for an electron beam storage system.
237, for addressing a memory with an electron beam.
