Abstract

A memory array of sixty-four cores is threaded with drive lines X1 ...X8 and Y1... Y8. Sense windings 10 and 11 are terminated at midpoint by characteristic impedances ZO 12 and ZO 13. Thus, when a sense signal is induced in windings 10 and 11, the part of the signal being sent away from differential amplifier 14 is absorbed. This allows only one signal to reach the amplifier for each core sensed.

Memory Array Sensing

A memory array of sixty-four cores is threaded with drive lines X1 ...X8 and Y1... Y8. Sense windings 10 and 11 are terminated at midpoint by characteristic impedances ZO 12 and ZO 13. Thus, when a sense signal is induced in windings 10 and 11, the part of the signal being sent away from differential amplifier 14 is absorbed. This allows only one signal to reach the amplifier for each core sensed.

Such eliminates the possibility of having two signals reach the amplifier at different times. Amplifier 14 is strobed by generator 15 and, together with the And 16, an output is only produced for a valid signal.
