Diagram of a 4×4 plane of magnetic-core memory in an X/Y line coincident-current setup. X and Y are drive lines, S is sense, Z is inhibit. Arrows indicate the direction of current for writing. Magnetic drum memories were developed for the US Navy during WW II with the work continuing at Engineering Research Associates (ERA) in 1946 and 1947.

DARPA SyNAPSE board with 16 TrueNorth chips. TrueNorth was a neuromorphic CMOS integrated circuit produced by IBM in 2014. [9] It is a manycore processor network on a chip design, with 4096 cores, each one having 256 programmable simulated neurons for a total of just over a million neurons.
Installing the magnetic drum in 1954 opened the way to develop a control program for running programs dealing with matrices. Following urging by J. M. Hahn [13] [14] of the British Aircraft Corporation, [15] Brian W. Munday developed General Interpretive Programme (GIP), which required only simple codewords to run a collection of programs called "bricks".
