Dab tsi yog RAM? | Random Saib Cov Lus Txhais

RAM sawv rau Random Access Memory , nws yog qhov tseem ceeb heev hauv hluav taws xob uas xav tau rau lub computer khiav, RAM yog ib hom kev cia uas CPU siv los khaws cov ntaub ntawv ua haujlwm tam sim no ib ntus. Nws tuaj yeem nrhiav tau hauv txhua hom khoom siv xws li Smartphones, PCs, ntsiav tshuaj, servers, thiab lwm yam.

Dab tsi yog RAM? | Random Saib Cov Lus Txhais

Txij li cov ntaub ntawv lossis cov ntaub ntawv nkag mus siv, kev nyeem thiab sau lub sijhawm tau nrawm dua piv rau lwm cov chaw khaws cia xws li CD-ROM lossis Hard Disk Drives qhov twg cov ntaub ntawv khaws cia lossis rov ua cov txheej txheem txuas ntxiv uas qeeb dua ib qho txheej txheem raws li cov ntsiab lus los khaws txawm tias me me ntawm cov ntaub ntawv khaws cia hauv nruab nrab ntawm cov txheej txheem peb yuav tsum tau mus thoob plaws ntu.



vim li cas yog discord noj so ntev los hloov

RAM xav tau lub hwj chim ua haujlwm, yog li cov ntaub ntawv khaws cia hauv RAM tau tshem tawm sai li sai tau thaum lub khoos phis tawm. Li no, kuj tseem paub tau zoo li Nco Sij Hawm los Cia Tsev Ib Ntus.

Ib lub Motherboard tuaj yeem muaj ntau lub cim xeeb ntawm cov qhov cim xeeb, qhov nruab nrab cov neeg siv khoom ntawm Motherboard yuav muaj nyob nruab nrab 2 thiab 4 ntawm lawv.

Txhawm rau Ua Cov Ntaub Ntawv lossis cov haujlwm yuav tsum ua tiav ntawm lub koos pij tawj, nws yuav tsum thauj khoom ua ntej ram.

Yog li cov ntaub ntawv lossis qhov program thawj khaws tseg rau hauv lub hard drive ces los ntawm lub hard drive, nws yog muab rov qab thiab thauj khoom rau hauv RAM. Thaum nws tau thauj khoom, lub CPU tam sim no tuaj yeem nkag mus rau cov ntaub ntawv lossis khiav qhov haujlwm tam sim no.

Muaj ntau cov ntaub ntawv lossis cov ntaub ntawv uas tau nkag mus tau ntau dua li lwm tus, yog tias lub cim xeeb qis dhau nws yuav tsis tuaj yeem tuav tag nrho cov ntaub ntawv uas CPU xav tau. Thaum qhov no tshwm sim tom qab ntawd qee cov ntaub ntawv tshaj dhau tau khaws cia rau hauv lub hard drive los them nyiaj rau qhov tsis tshua muaj kev nco.

Yog li hloov ntawm cov ntaub ntawv ncaj qha mus ntawm RAM mus rau CPU, nws yuav tsum khaws nws los ntawm lub hard drive uas muaj kev nkag tau qeeb heev, cov txheej txheem no maj mam poob lub computer. Qhov no tuaj yeem ua kom yooj yim los ntawm kev nce qib ntawm RAM uas muaj rau lub khoos phis tawm siv.

Ob Qhov sib txawv ntawm RAM

kuv) DRAM lossis RAM Dynamic

Dram yog lub cim xeeb uas muaj cov capacitors, uas zoo li lub thoob me me uas khaws hluav taws xob, thiab nws nyob hauv cov capacitors nws tuav cov ntaub ntawv. Vim tias cov yeeb yam muaj cov capacitors uas yuav tsum tau hloov kho dua tshiab nrog hluav taws xob tas li, lawv tsis tuav tus nqi rau lub sijhawm ntev heev. Vim tias cov capacitors yuav tsum tau hloov qhov hloov tshiab, qhov ntawd yog qhov uas lawv tau txais lub npe los ntawm. Daim foos ntawm RAM technology no tsis siv lawm vim yog txhim kho kom deb li deb thiab tau siv lub tshuab RAM ceev uas peb yuav tham txog ua ntej.

ii) SDRAM los yog Synchronous DRAM

Nov yog RAM tshuab uas siv dav hauv peb cov khoom siv hluav taws xob tam sim no. SDRAM kuj muaj lub zog xws li DRAM, li cas los xij, tus sib txawv ntawm SDRAM thiab DRAM yog qhov nrawm, qhov DRAM qub thev naus laus zis khiav qeeb qeeb los yog ua haujlwm asynchronously ntau dua li CPU, qhov no ua rau hloov mus ceev rau lag vim tias cov cim tsis sib raug zoo.

SDRAM khiav hauv sync nrog lub kaw lus moos, uas yog vim li cas nws sai dua li DRAM. Tag nrho cov cim ntsuas yog khi rau lub kaw lus moos rau lub sijhawm ntsuas tau zoo dua.

RAM tau txuas rau lub tshuab hluav taws xob (motherboard) nyob rau hauv daim ntawv ntawm tus neeg siv ntawm tshem cov modules uas tau hu ua SIMMs (Ib leeg nyob rau hauv kab nco modules) thiab DIMMs (dual hauv kab nco cim) Cov. Nws yog hu ua DIMMs vim tias nws muaj ob txoj kab ywj pheej ntawm cov pins ib qho ntawm txhua sab hos SIMMs tsuas muaj ib txoj kab pins ntawm ib sab. Ib sab ntawm tus qauv muaj ob qho 168, 184, 240 lossis 288 pins.

Cov kev siv ntawm SIMMs yog tam sim no dhau mus txij li lub cim xeeb muaj peev xwm ntawm RAM ob npaug nrog DIMMs Cov.

Cov DIMM no tuaj nyob rau hauv lub cim xeeb txawv, uas muaj nyob txhua qhov chaw ntawm 128 MB txog 2 TB. DIMMs hloov ntaub ntawv 64 me me ntawm Cov Ntaub Ntawv nyob rau ib lub sij hawm piv rau SIMMs uas hloov 32 me me ntawm Cov Ntaub Ntawv ib zaug.

SDRAM tseem tau ntsuas rau ntawm ntau lub sijhawm sib txawv, tab sis ua ntej peb delve rau ntawd, cia peb nkag siab tias cov ntaub ntawv kab yog dab tsi.

Kev nrawm ntawm CPU ntsuas nyob rau hauv moos caij nyoog, yog li hauv ib lub moos kev sib hloov, ib qho 32 lossis 64 me me ntawm cov ntaub ntawv tau hloov mus los ntawm CPU thiab RAM, qhov hloov pauv no hu ua cov kab kev.

Yog li ntawd lub moos ceev ceev ntawm lub CPU ntau dua lub khoos phis tawm yuav yog.

Zoo sib xws, txawm tias SDRAM muaj lub moos ceev ntawm qhov kev nyeem ntawv thiab sau ntawv tuaj yeem coj. Yog li qhov cuam tshuam ceev ntawm RAM lub moos ceev cov kev ua haujlwm tau sai dua tau txhawb nqa tus ua haujlwm. Qhov no yog ntsuas hauv cov lej ntawm qhov nws tuaj yeem ua tau suav hauv megahertz. Yog li, yog tias RAM tau ntsuas ntawm 1600 MHz, nws ua tau 1.6 billion mus rau ib thib ob.

Yog li, peb cia siab tias qhov no tau pab koj nkag siab li cas RAM thiab ntau hom RAM technologies ua haujlwm.
