A linear selection memory in which each word is driven independently from a multi-position switch might have the following advantages over a coincident current memory:
1. No outputs from non-selected cores.
2. No limitation to memory size by delta voltages.
3. Large unipolarity output voltage pulses.
4. Possibility of operation on saturation Φ-I loop.
5. Common z and sensing winding.
6. Simpler construction because only two windings are necessary per core.
An anti-coincident current switch which operates like the coincident current memory, but with the same lack of critical current adjustments as the magnetic matrix switch, is proposed to drive the memory.
