DRAM（Dynamic Random Access Memory），即动态随机存取存储器，最为常见的系统内存。
几乎所有的 DRAM 作为计算机系统中的离散元器件存在。DRAM 的硅工艺经过显著地定制，因此其无法与 CPU 一起集成。有许多样式的 DRAM 可满足市场的各种需要。双数据速率 DDR 存储器是台式机和服务器计算机中最常见的 DRAM 类型。DDR4 是最新一代的 DDR 存储器。低功率 DDR (LPDDR) 是移动和嵌入式系统首选的存储器技术。还有其他类型的 DRAM。
DRAM 单元只是一个存储电容器和访问晶体管。一个DRAM的存储单元存储的是0还是1取决于电容是否有电荷，有电荷代表1，无电荷代表0。但时间一长，代表1的电容会放电，代表0的电容会吸收电荷，这就是数据丢失的原因；刷新操作定期对电容进行检查，若电量大于满电量的1/2，则认为其代表1，并把电容充满电；若电量小于1/2，则认为其代表0，并把电容放电，藉此来保持数据的连续性。
