The Massachusetts Institute of Technology will receive $13 million in an out-of-court settlement of a patent-infringement suit, an M.I.T. spokesman announced yesterday.

He said that the International Busines Machine Corporation agreed last Friday to pay that amount as royalties for the use of a ferrite memory-core unit in high-speed computers. The settlement is the largest that M.I.T. has ever received.

Most of the money will be used for educational purposes, but part of it will go to Jay W. Forrester, professor of Industrial Management, who invented the memory unit and assigned the patent began in 1956, when it was developed.

A parallel suit against the Radio Corporation of America was also settled last week, but for a substantially smaller amount.
