Title
Early detection and repair of VRT and aging DRAM bits by margined in-field BIST
Abstract
We propose improving system availability by performing in-field repair at the chip level. This enables margining and detection of degrading memory cells before the user observes any errors. A 576 Mb embedded DRAM at 1.5 GHz in a 40nm CMOS technology achieves improved resilience to both aging memory cells and cells with variable retention time (VRT). Un-interrupted user access of 6 billion 72-bit read and write operations per second is maintained during background repair.
