An Electrically Alterable Nondestructive Twistor Memory

The twistor is a relatively new memory device which may be operated either in a conventional destructive read-out mode, or, by the method explained in this paper, in a nondestructive mode. This paper discusses the basic principles of twistor operation and shows how the twistor may be fabricated into a memory. A non-destructive method of reading a twistor memory by the use of multiple solenoids is described. A typical configuration of a twistor memory which, by the use of this nondestructive reading method, may be operated either in a destructive mode or in a nondestructive mode, is shown.
