A superconductive RAM memory design

A brief survey of contemporary superconductive RAMs (random-access memories) is given. A 16*1 RAM circuit which stores information with superconductive loop-currents that link unique pairs of connecting conductors is explained, read/write operations are described, and ways to minimize potential problems are suggested. In this RAM design, information is read out nondestructively, and the bit capacity of a node-pair circuit, with equal A and B matrices, is (n/sup 2/)/4, where n is the total number of connecting conductors (nodes) joining the AB plane. The minimum number of decoded address lines required is 4*(b/sup 0.25/), where b is the total bit capacity of the system.<>
