New Metallic Cores from Magnetic Metals
(MIT Digital Computer Laboratory, 1953-01-02)A preliminary test on 12, 1/4-mil molybdenum permalloy cores from Magnetic Metals indicates that signal ratios are unsatisfactory for memory application. Disturbed-one-to-disturbed-tero ratio is about 35; disturbed-one-t ... -
The noise problem in the coincident-current memory matrix
(Lincoln Laboratory - Division 6, 1956-02-13)Magnetic ferrites which have square hysteresis loops are being used as memory elements in high-speed digital computers. The limiting factor in memory reliability is the noise generated by the magnetic cores which are ... -
A Non-destructive Read System For Magnetic Cores
(MIT Digital Computer Laboratory, 1952-03-24)A non-destructive read system for magnetic cores is proposed which involves a quadrature field and which promises to be fast. -
