IMPLEMENTING ENHANCED MEMORY RELIABILITY USING MEMORY SCRUB OPERATIONS |
摘要 |
A method and circuit for implementing enhanced memory reliability using memory scrub operations to determine a frequency of intermittent correctable errors, and a design structure on which the subject circuit resides are provided. A memory scrub for intermittent performs at least two reads before moving to a next memory scrub address. A number of intermittent errors is tracked where an intermittent error is identified, responsive to identifying one failing read and one passing read of the at least two reads.
