Publication number: 20250209221Abstract: Systems and methods for providing standard cell yield information in a library (i.e., creating “defect-aware” libraries). The method includes accessing a library of a plurality of standard cells characterized on a foundry process node and revision. A geometric analysis is performed on individual ones of the standard cells to identify potential defects, such as shorts and opens. A defect is injected (i.e., “realized” or “actualized”) at the location of the identified potential defects. The standard cells in the library are then simulated with the defects injected to generate simulated yield information. Additionally, methods can access silicon failure analysis data representing test chips designed with the library and generate an inferred failure rate for the individual standard cells in the library, as a function of the silicon failure analysis and the simulated yield information.Type: ApplicationFiled: December 22, 2023Publication date: June 26, 2025Applicant: Intel CorporationInventors: Srikanth Venkat Raman, Pascal A. Meinerzhagen, Andrew Radcliffe, Jimmy Voong Liu, Jay Gandhi, Muhammad M. Khellah

Publication number: 20230123514Abstract: Embodiments herein relate to optimizing the duration of a sense amp enable signal in a memory device such as SRAM. A control circuit asserts the sense amp enable signal in response to a clock signal from a replica column of the SRAM. A feedback path extends from the sense amps back to the control circuit. In one approach, a change in a feedback signal on the feedback path indicates the sense amps have all received the sense amp enable signal. In another approach, a change in a feedback signal on the feedback path indicates the sense amps have all completed their sensing operations. In some cases, a selection can be made among multiple feedback paths.Type: ApplicationFiled: October 18, 2021Publication date: April 20, 2023Inventors: Gururaj K. Shamanna, Naveen Kumar M., Jagadeesh Chandra Salaka, Pascal A. Meinerzhagen, Sravan K. Puchakayala, Iqbal Rajwani
