Abstract
Design factors and operational features of a multiaperture ferrite memory core are discussed showing how a low coercive force, low switching coefficient material may be used for a high-speed coincident current storage device. The formulation, geometry, and important processing variables are given and a method of handling large numbers of asymmetrical cores for electrical test is described. Electromagnetic characteristics, pulse drive and bias test conditions are given. Data is presented showing the effect on core responses of varying net drive, pulse duration, half select drive and temperature. This device represents about a four-fold speed increase in comparison with present coincident current toroids.
