A Linear Selection Magnetic Memory Using an Anti-coincident Current Switch
Olsen, Kenneth H.
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.
