Title: Clay S. Johnson and His FPGA Invention

Introduction

Clay S. Johnson is an inventor associated with Xilinx, Inc. in San Jose, California. His patent work addresses how partially defective field-programmable gate arrays (FPGAs) can still be useful.

Latest Patents

Johnson is credited with 1 patent, titled “Method of Using Partially Defective Programmable Logic Devices.” The method tests whether an FPGA with a localized defect can accurately execute a particular design when that design does not rely on the defective area. If the device passes, it can be designated as suitable for that design. If it does not, other designs can be tested. This approach could allow manufacturers to sell some devices that might otherwise be discarded, potentially at a lower price.

Career Highlights

Johnson’s listed company affiliation is Xilinx, Inc. His patent reflects an approach to making use of programmable logic devices despite localized defects.

Collaborations

Jae Cho and Robert W. Wells are identified as Johnson’s coworkers.

Conclusion

Clay S. Johnson’s patent describes a way to test and match partially defective FPGAs with designs they can execute reliably, potentially reducing waste and expanding the usable supply of programmable logic devices.
