Title: Gerhard Grassl: Innovator in Semiconductor Technology
Introduction
Gerhard Grassl is a notable inventor based in Munich, Germany. He has made significant contributions to the field of semiconductor technology, holding 2 patents that showcase his innovative approach to logic circuitry and data processing technology.
Latest Patents
One of his latest patents is a method and arrangement for an operational check of a programmable logic. This invention allows for a function check of a programmable logic array, where input lines, product term lines, and ground lines are combined into an AND plane, while output lines, product term lines, and ground lines are combined into an OR plane. The method aims to provide a simple function check that can detect any potentially existing faults. The check is achieved by generating bit patterns with a test data generator and applying them to the input lines. A shift register is used to successively sensitizing the product term lines, either individually or in groups, disconnecting them from ground potential. The resulting bit patterns at the output lines are then supplied to a test data evaluator, making this invention particularly useful in logic circuitry of data processing technology.
Another significant patent by Grassl is for a capacitor semiconductor storage circuit. This invention features a plurality of storage elements equipped with storage capacitors, organized in rows and columns, and integrated on a doped semiconductor body. The storage elements in a row share a common first drive line, while those in a column share a second common drive line. The design includes strip-like electrically conductive layers separated by an insulating layer, with buried lines extending within the semiconductor body. The insulating layer is thinner in the intersection zones of the drive lines, forming insulating layer capacitors that serve as storage capacitors for the storage elements.
