Random nkag nco, lossis random nkag nco (RAM) yog siv los khaws cov txiaj ntsig nruab nrab ntawm kev ua haujlwm ntawm lub hauv paus nqa thiab daim npav ua ke video. Qhov ceev thiab kev ntseeg siab ntawm lub khoos phis tawm yog nyob ntawm seb tus yam ntxwv ntawm RAM.
Cov Lus Qhia
Kauj ruam 1
Tus txheej txheem, RAM module yog qhov nqaim multilayer sawb ntawm textolite, ntawm uas lub cim xeeb microcircuits, cov ntawv luam tawm Circuit Court nrog thov cov khoom siv thiab cov txuas txuas tau tso rau. Yog hais tias lub cim xeeb chips yog soldered mus rau RAM sawb tsuas yog ntawm ib sab, tus qauv hu ua ib leeg, yog tias ntawm ob sab nws yog hu ua ob tog.

RAM hu ua volatile nco vim tias nws rov qab pib rau xoom thaum nws txiav tawm ntawm lub hwj huam mov. Cov motherboard tseem muaj lub cim xeeb tsis haum, lossis nyeem nkaus xwb (ROM), uas lub zog siv roj teeb.

Zoo li txhua yam khoom siv hluav taws xob, lub cim xeeb ua kom sov thaum lub sijhawm ua haujlwm, uas ua rau lawv poob qis. Qee cov chaw tsim khoom tso cov dej kub ntawm cov qauv hluav taws xob kom zoo dua kom sov. Cov xaim hluav taws xob tuaj yeem txuas rau microcircuits lossis txuas rau ntawm cov ntawv xov uas siv cov nplais ntsej muag.

Cim xeeb txawv hauv hom. Tam sim no muaj 3 hom RAM hauv kev siv: DDR, DDR2 thiab DDR3. DDR nco tau nyob rau hauv ntau lawm txij li xyoo 2001. Nws tuaj yeem hloov 2 kab ntawv ntawm cov ntaub ntawv rau daim ntawv teev xov tooj nrog lub kaw lus nruab nrab thiab daim npav video hauv ib lub voj voog ntawm lub cim xeeb tsheb npav. Nws lub tshuab txuas tau muaj 184 pins. Lub zog tom ntej ntawm RAM yog DDR2 nco nrog 240 pins ntawm lub qhov (socket), uas xa cov 4 kab ib xuaj moos hauv kev voj voog. DDR3 nco hloov chaw 8 lub sijhawm ib lub moos.

Ntxiv rau, RAM modules sib txawv hauv cov qauv hauv. Txhua tus qauv motherboard yog tsim los ua haujlwm nrog ib hom kev nco. Txhawm rau tiv thaiv cov ua yuam kev txuas ntawm RAM tsis sib haum nrog lub motherboard no, txiav me me yog ua rau ntawm tus qauv txuas txuas, qhov hu ua. Ib "qhov tseem ceeb" uas phim rau "qhov tseem ceeb" ntawm RAM lub qhov (socket) ntawm motherboard. Tam sim no tsis muaj cov motherboard uas tsim los ua haujlwm nrog DDR nco.

Cov yam ntxwv tseem ceeb ntawm RAM yog lub peev xwm thiab moos ceev. Qhov ntsuas siab dua, cov ntaub ntawv ceev nrawm yuav siv sijhawm. Yog tias qhov sib txawv ntawm RAM modules tau teeb tsa rau lub motherboard, lub khoos phis tawm yuav khiav ntawm qhov nrawm ntawm qhov qeeb tshaj plaws. Yuav kom nce kev ua tau zoo, nws yog qhov zoo uas yuav tsum xaiv cov tib lub ntsuas hluav taws xob hauv tib qhov chaw ib hnub uas tau sim los ua haujlwm ua ke. Cov khoom siv no hu ua KITs.
