Abstract : An apparent remanent signal seen by the application of voltage pulses to a Sawyer-Tower circuit is described. This remanent is present for two pulses in the same direction when no remanent is expected. Variation of this signal with fatigue and ageing will be shown. Implications for memory circuits will also be discussed. Finally, several suggestions of possible mechanisms will be presented.
