MAGNETIC ROD READ ONLY MEMORY

摘要

A row by column read only memory matrix utilizes etched magnetic rods as the memory elements of the matrix. Each rod is divided into a given number of equilength ordered sections and the rods are positioned so that corresponding sections of each rod are in alignment. In this manner the rods form the rows of the matrix and the aligned sections from the columns of the matrix. A coil is wound around each row of the matrix. Various circuits are shown by which the read only memory can be operated with either a parallel output or a serial output.
