評(ping)價內(nei)存條的性能(neng)指標(biao)一共(gong)有四個:
(1) 存(cun)(cun)(cun)(cun)儲(chu)(chu)(chu)容量:即一(yi)根內存(cun)(cun)(cun)(cun)條可以容納(na)的(de)(de)二進制信息量,如常用的(de)(de)168線(xian)內存(cun)(cun)(cun)(cun)條的(de)(de)存(cun)(cun)(cun)(cun)儲(chu)(chu)(chu)容量一(yi)般多為(wei)32兆、64兆和128兆。而DDRII3普遍(bian)為(wei)1GB到8GB。 (2) 存(cun)(cun)(cun)(cun)取速度(存(cun)(cun)(cun)(cun)儲(chu)(chu)(chu)周(zhou)(zhou)期):即兩次(ci)獨立的(de)(de)存(cun)(cun)(cun)(cun)取操(cao)作(zuo)之(zhi)間(jian)(jian)(jian)(jian)(jian)所需的(de)(de)最(zui)短時(shi)間(jian)(jian)(jian)(jian)(jian),又稱為(wei)存(cun)(cun)(cun)(cun)儲(chu)(chu)(chu)周(zhou)(zhou)期,半導體存(cun)(cun)(cun)(cun)儲(chu)(chu)(chu)器(qi)的(de)(de)存(cun)(cun)(cun)(cun)取周(zhou)(zhou)期一(yi)般為(wei)60納(na)秒至100納(na)秒。 (3) 存(cun)(cun)(cun)(cun)儲(chu)(chu)(chu)器(qi)的(de)(de)可靠(kao)性:存(cun)(cun)(cun)(cun)儲(chu)(chu)(chu)器(qi)的(de)(de)可靠(kao)性用平均故(gu)障間(jian)(jian)(jian)(jian)(jian)隔(ge)時(shi)間(jian)(jian)(jian)(jian)(jian)來衡量,可以理(li)解(jie)為(wei)兩次(ci)故(gu)障之(zhi)間(jian)(jian)(jian)(jian)(jian)的(de)(de)平均時(shi)間(jian)(jian)(jian)(jian)(jian)間(jian)(jian)(jian)(jian)(jian)隔(ge)。 (4)性能(neng)價(jia)格比(bi):性能(neng)主要(yao)包括存(cun)(cun)(cun)(cun)儲(chu)(chu)(chu)器(qi)容量、存(cun)(cun)(cun)(cun)儲(chu)(chu)(chu)周(zhou)(zhou)期和可靠(kao)性三項內容,性能(neng)價(jia)格比(bi)是一(yi)個綜(zong)合性指標(biao),對于不同的(de)(de)存(cun)(cun)(cun)(cun)儲(chu)(chu)(chu)器(qi)有不同的(de)(de)要(yao)求。
