Patents by Inventor Torsten Schaefer

Torsten Schaefer has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 9171113
    Abstract: Methods and systems are provided for computing IR drop, i.e., voltage drop, in a semiconductor device. The method includes generating a modeling element corresponding to the plurality of transistors. At least one of the transistors in the modeling element is replaced with a current source. The method also includes performing an IR drop analysis of the modeling element utilizing a software program to calculate the IR drop in the semiconductor device.

  • Patent number: 9076552
    Abstract: A device includes a substrate and a dual port static random access memory cell. The substrate includes an N-well region, a first P-well region and a second P-well region. The first and second P-well regions are arranged on opposite sides of the N-well region and spaced apart along a width direction. The static random access memory cell includes first and second pull-up transistors that are provided in the N-well region, a first pair of pull-down transistors and a first pair of access transistors provided in the first P-well region, and a second pair of pull-down transistors and a second pair of access transistors provided in the second P-well region. Each of the first pair and the second pair of pull-down transistors includes a first pull-down transistor and a second pull-down transistor. Active regions of the first pull-down transistor and the second pull-down transistor are spaced apart along the width direction.
