Abstract
In memory reads, an increase in a number of correctable errors increases a likelihood that an uncorrectable error will occur. Thus, tracking of correctable errors per memory page is one technique that can be used and if the number of errors on a memory page exceeds a threshold then the memory page can be replaced through dynamic memory re-mapping. However, having a counter per memory page to track the errors is costly due to the number of memory pages. Accordingly, a system is proposed wherein a group of counters is used that acts as a cache of counters that track memory pages of interest due to a variety of factors. Additionally, an eviction policy can control which memory pages are tracked so that only the most interesting candidate pages can be tracked in accordance with a policy.
