          			DRAM（Dynamic Random Access Memory），即動態隨機存取存儲器，最為常見的系統內存。
          幾乎所有的 DRAM 作為計算機系統中的離散元器件存在。DRAM 的硅工藝經過顯著地定制，因此其無法與 CPU 一起集成。有許多樣式的 DRAM 可滿足市場的各種需要。雙數據速率 DDR 存儲器是臺式機和服務器計算機中最常見的 DRAM 類型。DDR4 是最新一代的 DDR 存儲器。低功率 DDR (LPDDR) 是移動和嵌入式系統首選的存儲器技術。還有其他類型的 DRAM。
           
           
            
           
           
           
           
          DRAM 單元只是一個存儲電容器和訪問晶體管。一個DRAM的存儲單元存儲的是0還是1取決于電容是否有電荷，有電荷代表1，無電荷代表0。但時間一長，代表1的電容會放電，代表0的電容會吸收電荷，這就是數據丟失的原因；刷新操作定期對電容進行檢查，若電量大于滿電量的1/2，則認為其代表1，并把電容充滿電；若電量小于1/2，則認為其代表0，并把電容放電，藉此來保持數據的連續性。
