Jay Forrester patents magnetic-core memory
28th February 1956
In 1949 Jay Forrester devised a memory system that used rings of magnetic material to store data.
On 28th February 1956, Forrester was awarded patent number 2,736,880 for his coincident current magnetic core memory.
Forrester's random-access magnetic-core memory was faster and more reliable than pervious memory technologies. Magnetic-core memory remained the predominant form of computer memory storage until it was replaced by solid state RAM in the 1970s.
