評價內(nei)存條的性能指標一(yi)共有四個:
(1) 存(cun)(cun)(cun)(cun)(cun)儲(chu)容(rong)量:即一根內(nei)存(cun)(cun)(cun)(cun)(cun)條可(ke)以容(rong)納的(de)(de)(de)二進制信息量,如常用的(de)(de)(de)168線內(nei)存(cun)(cun)(cun)(cun)(cun)條的(de)(de)(de)存(cun)(cun)(cun)(cun)(cun)儲(chu)容(rong)量一般(ban)多(duo)為32兆、64兆和128兆。而DDRII3普(pu)遍為1GB到8GB。 (2) 存(cun)(cun)(cun)(cun)(cun)取(qu)速度(存(cun)(cun)(cun)(cun)(cun)儲(chu)周期(qi)):即兩次獨(du)立的(de)(de)(de)存(cun)(cun)(cun)(cun)(cun)取(qu)操作之(zhi)間(jian)(jian)所需的(de)(de)(de)最(zui)短時(shi)間(jian)(jian),又稱(cheng)為存(cun)(cun)(cun)(cun)(cun)儲(chu)周期(qi),半導體存(cun)(cun)(cun)(cun)(cun)儲(chu)器(qi)(qi)(qi)的(de)(de)(de)存(cun)(cun)(cun)(cun)(cun)取(qu)周期(qi)一般(ban)為60納秒(miao)至(zhi)100納秒(miao)。 (3) 存(cun)(cun)(cun)(cun)(cun)儲(chu)器(qi)(qi)(qi)的(de)(de)(de)可(ke)靠性(xing)(xing)(xing)(xing):存(cun)(cun)(cun)(cun)(cun)儲(chu)器(qi)(qi)(qi)的(de)(de)(de)可(ke)靠性(xing)(xing)(xing)(xing)用平(ping)均(jun)故(gu)障間(jian)(jian)隔(ge)時(shi)間(jian)(jian)來衡量,可(ke)以理解為兩次故(gu)障之(zhi)間(jian)(jian)的(de)(de)(de)平(ping)均(jun)時(shi)間(jian)(jian)間(jian)(jian)隔(ge)。 (4)性(xing)(xing)(xing)(xing)能(neng)價格比:性(xing)(xing)(xing)(xing)能(neng)主(zhu)要包括存(cun)(cun)(cun)(cun)(cun)儲(chu)器(qi)(qi)(qi)容(rong)量、存(cun)(cun)(cun)(cun)(cun)儲(chu)周期(qi)和可(ke)靠性(xing)(xing)(xing)(xing)三(san)項(xiang)內(nei)容(rong),性(xing)(xing)(xing)(xing)能(neng)價格比是一個(ge)綜合性(xing)(xing)(xing)(xing)指標,對于(yu)不(bu)同的(de)(de)(de)存(cun)(cun)(cun)(cun)(cun)儲(chu)器(qi)(qi)(qi)有不(bu)同的(de)(de)(de)要求(qiu)。
