Abstract

A broad range of magnetic memories finds extensive use in today’s data processing equipment. The most significant factors in evaluating a memory for a given application are reliability, cost, size, speed, and function. Ferrite core memories with capacities of 103 to 106 bits and with cycle times as short as 0.5 μsec are in use. Recent developments in this area, including partial switching, 2 cores/bit, and new core fabrication techniques, will be discussed.
