Development of a 10,000,000 Bit Magnetic Film Memory

Abstract

Batch fabrication techniques for making 200,000 bit substrates with word lines integral with a closed magnetic film structure and keepered digit lines on large area substrates are described. A sense amplifier was designed which does not require a transformer for impedance matching to the digit lines. Cross-section-stack tests proved the feasibility of a 10 million bit memory with 1.0 microsecond cycle time. All fabrication processes are consistent with the goal of low memory construction costs.
