RESEARCH ON LOW-POWER MAGNETIC-FILM MEMORIES.
Abstract
The objective is to demonstrate the feasibility of fabricating microminiaturized evaporated circuitry for use with the low-power magneticfilm memory elements. Passivated chip transis tors with attached leads were obtained, and an evaporated bit driver incorporating these units was successfully operated. Several sense amplifiers were evaporated, and an improved amplifier is being designed. The design of a word-selection system was completed, and breadboard models of representative portions were constructed and tested with satisfactory results. Techniques for the preparation of evaporated resistors were improved; resistance values can be reproduced to within plus or minus 5 %. Capacitors were also successfully evaporated; capacitance values can be reproduced to within plus or minus 4%. The design of the memory array was modified to reduce interline coupling. Magnetic films with substantially reduced skew and dispersion were obtained. (Author)
