MATRIX STORAGE CIRCUIT OF PERMANENT STORAGE Russian patent published in 1994 - IPC

FIELD: computer engineering. SUBSTANCE: invention can be used in permanent storage re-programmed electrically and keeping up information when power supply source is disconnected. It is targeted at simplification of matrix storage circuit. This is achieved due to fabrication of discharge wires 15 from metal and due to their positioning on surface of fifth dielectric layer 11 and on surfaces of other diffusion regions 5 of second type of conductance with gap with respect to diffusion wires 6 with protrusions of second type of conductance. This makes it possible to make unnecessary third polysilicon layer of which other discharge polysilicon wires of known storage circuit and additional dielectric layer insulating polysilicon electrode 12 from other discharge polysilicon wires 15 are manufactured. EFFECT: simplified manufacture of matrix storage circuit. 3 dwg
