摘要： A magnetic bubble memory (of the type that has a magnetic film, a plurality of magnetic bubbles in the film, and an insulating layer over the film) includes an improved electromagnetic structure on the insulating layer for stretching the bubbles to aid in their detection; which structure is comprised of a plurality of elongated permalloy elements on the insulator and arranged in spaced apart rows with only one of the elements per row; each element has a pattern that is X-shaped which repeats along the element in the direction of elongation; the X in the pattern has two short legs and two long legs; and the pattern is repeated such that the short legs of one X join with the long legs of the next X.

摘要： This disclosure relates to a programmable logic array having an AND array disposed for receiving n input signals, an OR array providing k output signals on k output lines and m term lines coupling the AND and OR arraystogether. Newand improved AND and OR arrays are disclosed wherein the AND array includes n X m cells and each cell has first and second transistor means coupled in series between one of the term lines and a reference potential. Each cell includes a storage element that has an output terminal coupled to the control element of the first transistor means and one of the n input terminals is coupled to the control element of the second transistor means. The OR array includes m X k cells wherein each cell has third and fourth transistor means coupled in series between one of said output lines and a reference potential. Each of the OR array cells also includes a storage element having an output terminal coupled to the control element of the third transistor and one of the m term lines is coupled to the control element of the fourth transistor.

摘要： A magnetic bubble memory includes a planar magnetic film containing a plurality of magnetic bubbles which move in response to a magnetic field that rotates the film's plane; and further includes an improvided mechanism for detecting the bubbles comprised of: a pair of elongated magnetoresistive members that lie over the film alongside of one another; the members having fingers that extend towards each other along the direction of elongation; the fingers of one member being interdigitated with the fingers of the other member such that they mesh together but do not touch; the fingers being interdigitated at angles of less than 180° so that magnetic poles which attract the bubbles are sequentially induced in the fingers of only one member, in the fingers of both members, and in the fingers of only the other member by each rotation of the field.
