Title: Non-volatile electronic memory system - uses electron beam to warm magnetic cell above Curie temperature when value is changed
Inventor: WAGENER WOLFDIETER
IPC: G11B11/10
Filed: 1990-03-09
Abstract: The multi-layer construction includes a heating element (1) which provides a source of electrons. These are accelerated through charged plates (3,4,5) and electrostatically steered onto cells of magnetic material (12).
