Abstract

A plurality of individually fabricated memory planes, each of which includes a number of memory elements, is assembled end interconnected to form the complete memory. The interconnections are achieved using a flexible MYLAR* sheet, drawing A, on one side of which is affixed a ferrite keeper. On the other side of this sheet there are affixed the individual conductors for making the connections between the word and bit lines on the individual memory planes in the finally assembled memory. The conductors on the connecting sheet are maintained in contact with the word and bit lines by vacuum, as in drawing B. The connections between the memory elements on two ground planes 10 and 12 are shown. *Trademark of E. I. du Pont de Nemours and Co.

Flexible Interconnection for Thin Film Memory

A plurality of individually fabricated memory planes, each of which includes a number of memory elements, is assembled end interconnected to form the complete memory. The interconnections are achieved using a flexible MYLAR* sheet, drawing A, on one side of which is affixed a ferrite keeper. On the other side of this sheet there are affixed the individual conductors for making the connections between the word and bit lines on the individual memory planes in the finally assembled memory. The conductors on the connecting sheet are maintained in contact with the word and bit lines by vacuum, as in drawing B. The connections between the memory elements on two ground planes 10 and 12 are shown. *Trademark of E. I. du Pont de Nemours and Co. Each memory element on the individual ground planes is formed by two coupled films of NiFe between which the bit conductors extend. The word conductors are located on top of the memory element. Bit conductor interconnector 16 is maintained by the vacuum in contact with the two bit conductors on planes 14 and 16. The same is true for the word conductor interconnectors 18 on the flexible MYLAR connector sheet. A separate insulated conductor can also be provided on this sheet to achieve better electrical connections between the two abutting ground planes 10 and 12.
