Method of manufacturing 3-D memories

Abstract

A method of manufacturing triple coincidence access 3-D memories (requiring 3 inputs for memory access) which, according to the invention, consists in making a flat core matrix threaded along three directions of the Cartesian system, the matrix is then positioned opposite the place of manufacturing a subsequent flat matrix, every matrix is secured in the position provided for it in the 3-D memory being manufactured and in which the subsequent weaving procedure is carried out until the preset number of matrices for the 3-D memory is obtained. A device realizing the proposed procedure which comprises pick-up point assemblies securing wires along the Y-coordinate direction, a roll having a longitudinal guide made as a groove transverse to the wires, a mechanism coiling the wire that threads a row of cores along the X-coordinate direction, means for straightening the wire and for positioning the line of threaded cores in corresponding places of the flat matrix and which, according to the invention, is provided with a stack of threaded flat matrices positioned opposite the place of matrix threading, means for securing matrices, pick-up point assemblies to which the wires running along the Z-coordinate direction are attached with one end while the other end of every wire has a needle secured to it and all needles are fastened with intercepting combs, and means for inserting the needles into the holes of cores, said means being made as a guide directing the displacement of said intercepting comb.
