title="漏電流(页面不存在)">漏電流</a>的現象,導致電容上所儲存的電荷數量並不足以正確的判別数据,进而導致数据毀損。因此對於DRAM來說,周期性地充電是一個不可避免的条件。由於這種需要定時刷新的特性,因此被稱為「動態」記憶體。相對來說,靜態記憶體(<a href="/wiki/%E9%9D%99%E6%80%81%E9%9A%8F%E6%9C%BA%E5%AD%98%E5%8F%96%E5%AD%98%E5%82%A8%E5%99%A8" class="mw-redirect" title="静态随机存取存储器">SRAM</a>)只要存入数据後,即使不刷新也不會遺失記憶。 </p><p>DRAM與<a

title="電晶體">電晶體</a>來處理,而SRAM上一個位元通常需要六個電晶體。正因這緣故,DRAM擁有非常高的密度,單位體積的容量較高,成本也較低。但相反的,DRAM也有存取速度较慢,耗<a href="/wiki/%E7%94%B5%E9%87%8F" class="mw-redirect" title="电量">电量</a>较大的缺點。为了进一步提高速度,人们开发了同步(synchronous)DRAM或SDRAM,操作与外部时钟同步,以实现高速运行。如今,DRAM一般都指SDRAM。<sup id="cite_ref-2" class="reference"><a href="#cite_note-2"><span
