Dr. Michiko Inoue Gave a Talk on “An ECC-based memory architecture with online self-repair capabilities for reliability enhancement” at IICT, BUET on 8th March, 2016 at 5PM at the IICT Seminar Room


Embedded memory is extensively being used in SoCs, and is rapidly growing in size and density. To keep up with the development pace of nanoscale devices, enhancement methods for yield and reliability must overcome the barriers set forth by advent of new technology. To address the issue of reliability, periodic online field test and repair are implemented by using synergistic approach of employing redundancy and ECC to repair or correct both hard errors and soft errors. In this paper, an online remap strategy for memory repair, which ensures ‘fresh’ memory words are always used until the spare words run out, is proposed. The improvement of reliability for memory architectures and the area overhead introduced by the proposed scheme is evaluated.
