Abstract
A synergistic approach to mitigating crosstalk in a Dynamic Random-Access Memory (DRAM) implements the use of a random number generator to increment a counter in a probabilistic manner. The counter is formed by reclaiming bytes of a double data rate (DDR) fault isolation feature. The random number generator value may be compared against a predetermined parameter value and a determination may be made whether or not to extract and increment the counter based on a result of the comparison. A logic controller compares the counter value to a predetermined hotness threshold parameter and a flag is set based on an existence of an address match in local memory. Based on the results of the comparison, access to the DRAM is reduced.
