The impact of memory-management policies on memory reliability is discussed. The tradeoffs in performance and reliability are studied as a function of the block-miss reload time. A detailed analysis of how reliability is affected by the memory space allocated is presented. This can be used to understand the relationship between the amounts of memory allocated and reliability. Separate effects are measured, depending on the relative time to process a first-level memory miss. For very small memories, a very few page durations contribute to a majority of the total unreliability. Two techniques for further improving reliability are suggested to remove these long durations
