Charge leaks from a cell over time, even when software performs no reads or writes. A memory system therefore has to refresh DRAM periodically to preserve stored bits.</p> <p>Refresh is a maintenance operation rather than a request from an application. The memory controller and DRAM device coordinate it alongside ordinary reads and writes. During parts of that work, some memory resources cannot serve normal requests.</p>
