HALF-LEADING SYSTEM WITH PERMANENTMINE AND SEEN TO PROMOTE AN ANIMAL HALF-LEADING SYSTEM

摘要

In a diode matrix of a permanent memory (ROM) the word line and bit line system is formed by a system of strip-shaped zones of one conductivity type provided in the silicon body and in the another system is formed by polycrystalline silicon tracks of the opposite conductivity type provided on the surface and forming mono-poly p-n junctions with the strip-shaped zones. High packing density and high speed are obtained.
