Abstract:

The crosstie memory is intended for use as a block oriented random access memory BORAM or fast auxiliary memory FAM. The advantages of the crosstie memory are speed, low power, high bit density, nonvolatility, a wide temperature range of operation, low cost, and available technology. This report contains information on wall placement techniques, dynamic nucleation thresholds, propagation, microcircuitry, domain wall observation, and detection. Microcircuitry for shifting data has been developed and tested for 32-bit experimental shift registers. The information is observed using the magnetooptic Kerr effect. Detection is considered feasible using either magnetoresistance or guided wave optics.
