Abstract
In a magnetic bubble (domain) memory chip, transfer gating circuits of propagate elements oriented to be responsive to different phases of in-plane rotating magnetic field are operated by a single conductor which is subjected to current pulses during a specific phase of the rotating field cycle to transfer bubbles onto different bubble paths. The transfer gates perform their gating function only when a control current pulse occurs during a specific phase of the rotating field cycle and are unresponsive to the current pulses at other phase times on the same conductor which actuate other gates.
