  DRAM refresh
  
     <storage> The operation which cycles through a DRAM reading
     each row and writing it back again to compensate for the
     gradual leakage of charge from the capacitors which store
     the data.  This may be done by the CPU but is often done by
     a dedicated memory controller.
