WebMemory Refresh - How DRAM Refresh Works - Refresh Overhead Refresh Overhead The fraction of time the memory spends on refresh, the refresh overhead, can be calculated from the system timing: For example, a recent SDRAM chip has 213 = 8 192 rows, a refresh time of 64 ms, the memory bus runs at 133 MHz, and the refresh cycle takes 4 clock cycles. While the memory is operating, each memory cell must be refreshed repetitively, within the maximum interval between refreshes specified by the manufacturer, which is usually in the millisecond region. Refreshing does not employ the normal memory operations (read and write cycles) used to access data, but specialized cycles called refresh cycles which are generated by separate counter circuits in the memory circuitry and interspersed between normal memory acc…
