評(ping)價內存條的(de)性能指(zhi)標一共有四(si)個:
(1) 存(cun)(cun)(cun)(cun)儲(chu)容量(liang)(liang):即一(yi)根內(nei)存(cun)(cun)(cun)(cun)條可以(yi)容納(na)(na)的(de)(de)(de)二進制信息量(liang)(liang),如(ru)常用的(de)(de)(de)168線內(nei)存(cun)(cun)(cun)(cun)條的(de)(de)(de)存(cun)(cun)(cun)(cun)儲(chu)容量(liang)(liang)一(yi)般多為(wei)(wei)32兆(zhao)、64兆(zhao)和128兆(zhao)。而DDRII3普遍為(wei)(wei)1GB到(dao)8GB。 (2) 存(cun)(cun)(cun)(cun)取速度(存(cun)(cun)(cun)(cun)儲(chu)周(zhou)期):即兩次獨立的(de)(de)(de)存(cun)(cun)(cun)(cun)取操作之(zhi)間(jian)(jian)(jian)(jian)所需(xu)的(de)(de)(de)最短時(shi)間(jian)(jian)(jian)(jian),又稱為(wei)(wei)存(cun)(cun)(cun)(cun)儲(chu)周(zhou)期,半導(dao)體(ti)存(cun)(cun)(cun)(cun)儲(chu)器(qi)的(de)(de)(de)存(cun)(cun)(cun)(cun)取周(zhou)期一(yi)般為(wei)(wei)60納(na)(na)秒至100納(na)(na)秒。 (3) 存(cun)(cun)(cun)(cun)儲(chu)器(qi)的(de)(de)(de)可靠性(xing)(xing):存(cun)(cun)(cun)(cun)儲(chu)器(qi)的(de)(de)(de)可靠性(xing)(xing)用平均故(gu)障(zhang)(zhang)間(jian)(jian)(jian)(jian)隔時(shi)間(jian)(jian)(jian)(jian)來衡(heng)量(liang)(liang),可以(yi)理解為(wei)(wei)兩次故(gu)障(zhang)(zhang)之(zhi)間(jian)(jian)(jian)(jian)的(de)(de)(de)平均時(shi)間(jian)(jian)(jian)(jian)間(jian)(jian)(jian)(jian)隔。 (4)性(xing)(xing)能價格比:性(xing)(xing)能主要包括(kuo)存(cun)(cun)(cun)(cun)儲(chu)器(qi)容量(liang)(liang)、存(cun)(cun)(cun)(cun)儲(chu)周(zhou)期和可靠性(xing)(xing)三(san)項內(nei)容,性(xing)(xing)能價格比是一(yi)個綜合性(xing)(xing)指(zhi)標,對于不(bu)同的(de)(de)(de)存(cun)(cun)(cun)(cun)儲(chu)器(qi)有不(bu)同的(de)(de)(de)要求。
