Title: Innovations of Lawrence G Zierhut
Introduction
Lawrence G Zierhut is a notable inventor based in Eagan, Minnesota, recognized for his contributions to magnetic memory systems. With a total of three patents to his name, Zierhut has made significant advancements in the field of data storage technology.
Latest Patents
Zierhut's latest patents include a Y-domain magnetic memory system. This innovative memory system incorporates a memory element that stores binary digital data in the presence or absence of a Y-domain cross-tie. The design features a planar contour that is symmetrical about a longitudinal axis, with edge portions that are neither perpendicular nor parallel to this axis. A stabilizing magnetic field applied perpendicular to the longitudinal axis forms a first Neel wall, leading to the creation of first and second domains on either side of the Neel wall. The introduction of a writing magnetic field results in a third domain, enhancing the readout signal's difference between stored binary values compared to previous technologies.
Another significant patent is the nondestructive readout, random access cross-tie wall memory system. This system consists of multiple discrete thin ferromagnetic film memory elements, where binary data is stored as the presence or absence of cross-tie, Bloch-line pairs. The memory elements are organized in a matrix array, allowing for efficient data retrieval through a coincident row line read drive field and a column read current signal.
