Resident-Bubble Cellular Logic Using Magnetic Domains
April 1972 (vol. 21 no. 4)
pp. 392-396
M. R. Garey, Bell Telephone Laboratories, Inc., Murray Hill, N. J.
A new approach to the design of complex logic circuitry using magnetic bubbles is described. The method is based on the construction of cells that perform simple logical operations and that can be combined to realize more complex functions. An important property of these cells is that no bubbles ever enter or leave any cell, all intercell communications being accomplished by bubble interactions near the cell boundaries. Illustratively, a set of four basic cells is described which is sufficient to realize all combinatorial and sequential switching functions. The cells possess an important synchronization property that allows them to be combined in a manner quite similar to combining semiconductor gates in current technology.
