FEASIBILITY STUDY FOR A THIN FILM MEMORY SYSTEM
Abstract
The object of this project is to design and develop a feasibility test model of a small, thin film digital memory. The model is to be a 4 word, 2 bits/word, nondestructive, linear select memory. Readout and write-in is to be in parallel at a clock frequency of 5 mc, and addressing was to be sequential. The memory element to be used is the toroidal thin film Ni-Fe-Co "toristor". The toristor is a thin film Ni-Fe-Co cylinder which has been plated on either a glass capillary tube or a stainless steel hypodermic tube. Though its switching characteristics are similar to the planar dot memory element, it offers the following advantages: (1) a much larger output signal; (2) nondestructive read characteristic; (3) relative freedom from the destructive effect of strong magnetic field.
