Patent 9,099,164: IBM Secures Innovations in Capacitor Backup for SRAM Technology

Strategic Insights -

On August 4, 2015, the United States Patent and Trademark Office granted patent no. 9,099,164 to International Business Machines Corporation (IBM) of New York, titled "Capacitor backup for SRAM." The innovative technology, developed by a team of IBM inventors, including Karl R. Erickson, Phil C. Paone, David P. Paulsen, John E. Sheets, Gregory J. Uhlmann, and Kelly L. Williams, aims to revolutionize the way data is backed up in Static Random Access Memory (SRAM) devices.

The patented method utilizes a capacitive backup circuit to safeguard data in SRAM cells, offering an efficient and reliable solution for data preservation. The technology enables the backup of data written to SRAM cells by electrically coupling the input node to the capacitive backup circuit and restoring the data stored in the backup circuit to the SRAM cell.
