ABSTRACT:
A magnetic bubble domain chip layout or organization which achieves consecutive bit access is provided by arranging the device in two substantially identical halves or parts. Each half contains half of the total number of storage loops, a separate access loop with its own generator, switches between the storage loop and an access loop, and a separate detector. The separate detectors are connected together to form two arms of a single bridge wherein consecutive bit output is achieved. The generators in each half of the device are located at different distances from the switches between the loops in one half of the device and the associated access loop. In addition, each of the detectors is located a different distance from the switches in the respective halves or parts of the device.
