Implementing DRAM command timing adjustments to alleviate DRAM failures

摘要

A method, system and computer program product are provided for implementing command timing adjustments to alleviate Dynamic Random Access Memory (DRAM) failures in a computer system. A predefined DRAM failure is detected. Responsive to the detected failure, a set of timers is adjusted for controlling predetermined timings used to access the DRAM. Responsive to the failure being resolved by the adjusted set of timers, checking for a predetermined level of performance is performed.

1. A method for implementing command timing adjustments to alleviate Dynamic Random Access Memory (DRAM) failures in a computer system comprising:
detecting a predefined DRAM failure; responsive to detecting the predefined DRAM failure, adjusting a set of timers for controlling predetermined timings used to access DRAM including selectively providing predetermined adjustment values from characterization or relaxed to include a set percentage of margin; and responsive to the predefined DRAM failure being resolved by the adjusted set of timers, checking for a predetermined level of performance.
