Hauv ntiaj teb digital niaj hnub no, cov ntaub ntawv ncaj ncees thiab kev ntseeg tau yog qhov tseem ceeb.Txawm hais tias nws yog lub server, chaw ua haujlwm lossis lub khoos phis tawj ua haujlwm siab, kom ntseeg tau qhov tseeb thiab sib xws ntawm cov ntaub ntawv khaws cia yog qhov tseem ceeb.Qhov no yog qhov yuam kev Kho Code (ECC) RAM los ua si.ECC RAM yog ib homnco uas muab kev txhim kho cov ntaub ntawv kev ncaj ncees thiab kev tiv thaiv kev sib kis tsis raug.
ECC RAM yog dab tsi?Nws ua li cask?
ECC RAM, luv luv rau Error Correcting Code RAM, yog lub cim xeeb module uas muaj cov kab hluav taws xob ntxiv txhawm rau txheeb xyuas thiab kho qhov yuam kev uas yuav tshwm sim thaum cov ntaub ntawv xa mus thiab khaws cia.Nws yog feem ntausiv rau hauv cov ntawv thov tseem ceeb xws li servers, kev tshawb fawb suav, thiab cov tuam txhab nyiaj txiag, qhov twg txawm tias qhov yuam kev me me tuaj yeem ua rau muaj qhov tshwm sim loj.
Yuav kom nkag siab li casECC RAM ua haujlwm, cia peb xub nkag siab luv luv ntawm lub hauv paus ntawm lub computer nco.Random access memory (RAM) yog ib hom kev nco tsis zoo uas khaws cov ntaub ntawv ib ntus thaum lub computer siv nws.Thaum CPU (Central Processing Unit) xav tau nyeem lossis sau cov ntaub ntawv, nws nkag mus rau cov ntaub ntawv khaws cia hauv RAM.
Ib txwm RAM modules(hu ua non-ECC lossis ib qho RAM) siv ib qho me me ntawm lub cim xeeb ntawm tes los khaws thiab hloov cov ntaub ntawv.Txawm li cas los xij, cov chaw khaws cia no ua rau muaj qhov yuam kev yuam kev uas tuaj yeem ua rau cov ntaub ntawv kev noj nyiaj txiag lossis kev sib tsoo.ECC RAM, ntawm qhov tod tes, ntxiv ib theem ntxiv ntawm kev kho qhov yuam kev rau lub cim xeeb module.
ECC RAM tso cai rau kev tshawb nrhiav thiab kho qhov yuam kev los ntawm kev siv cov khoom cim xeeb ntxiv los khaws cov ntaub ntawv sib luag lossis qhov yuam kev.Cov khoom ntxiv no suav nrog raws li cov ntaub ntawv khaws cia hauv lub cim xeeb ntawm tes thiab siv los txheeb xyuas qhov tseeb ntawm cov ntaub ntawv thaum nyeem thiab sau operations.Yog tias kuaj pom qhov yuam kev, ECC RAM tuaj yeem txiav thiab pob tshab kho qhov yuam kev, kom ntseeg tau tias cov ntaub ntawv khaws cia tseem raug thiab tsis hloov pauv.Qhov no feature txawv ECC RAM los ntawm ib txwm RAM vim hais tias nws muab ib tug ntxiv txheej ntawm kev tiv thaiv ntawm lub cim xeeb yuam kev.
Txoj kev siv ECC feem ntau yog kev kho ib qho kev ua yuam kev, ob qhov kev ua yuam kev (SEC-DED).Hauv cov tswv yim no, ECC RAM tuaj yeem txheeb xyuas thiab kho qhov yuam kev ib-ntsis uas yuav tshwm sim hauv lub cim xeeb.Tsis tas li ntawd, nws tuaj yeem kuaj xyuas yog tias qhov yuam kev ob npaug tau tshwm sim, tab sis tsis tuaj yeem kho nws.Yog tias pom qhov yuam kev ob-ntsis, lub kaw lus feem ntau tsim cov lus yuam kev ib qhod yuav siv sij hawm tsim nyog, xws li lub kaw lus reboot lossis hloov mus rau qhov system thaub qab.
Ib qho ntawm cov khoom tseem ceeb ntawm ECC RAM yog lub cim xeeb tswj, uas ua lub luag haujlwm tseem ceeb hauv kev txheeb xyuas qhov yuam kev thiab kho.Tus tswj lub cim xeeb yog lub luag haujlwm rau kev suav thiab khaws cov ntaub ntawv sib luagation thaum sau ntawv ua haujlwm thiab txheeb xyuas cov ntaub ntawv sib luag thaum nyeem cov haujlwm.Yog tias kuaj pom qhov yuam kev, tus tswj lub cim xeeb tuaj yeem siv lej algorithms los txiav txim seb cov khoom twg yuav tsum tau kho thiab kho cov ntaub ntawv raug.
Nws yog ib qho tsim nyog sau cia tias ECC RAM yuav tsum tau siv lub cim xeeb sib xws thiab cov motherboard uas txhawb nqa ECC kev ua haujlwm.Yog tias ib qho ntawm cov khoom no ploj lawm, tsis tu ncua ECC RAM tuaj yeemsiv los hloov, tab sis tsis muaj qhov txiaj ntsig ntxiv ntawm kev tshawb nrhiav thiab kho.
Txawm hais tias ECC RAM muab kev kho qhov yuam kev siab heev, nws kuj muaj qee qhov tsis zoo.Ua ntej, ECC RAM yog me ntsis kim dua li niaj zaus uas tsis yog-ECC RAM.Ntxiv circuitry thiab yuam kev kho complex ua rau cov nqi ntau lawm.Qhov thib ob, ECC RAM ua rau muaj kev nplua me ntsis vim qhov nyiaj siv ua haujlwm ntawm kev ua yuam kev hauv kev suav.Txawm hais tias qhov cuam tshuam ntawm kev ua tau zoo feem ntau me me thiab feem ntau tsis saib xyuas, nws tsim nyog xav txog cov ntawv thov uas ceev yog qhov tseem ceeb.
ECC RAM yog hom tshwj xeeb ntawm lub cim xeeb uas muab cov ntaub ntawv zoo tshaj plaws thiab kev tiv thaiv kev sib kis tsis raug.Los ntawm kev siv cov khoom siv yuam kev ntxiv thiab cov algorithms siab heev, ECC RAM tuaj yeem kuaj xyuas thiab kho qhov yuam kev, kom ntseeg tau qhov tseeb thiab kev ntseeg siab ntawm cov ntaub ntawv khaws cia.Txawm hais tias ECC RAM yuav raug nqi me ntsis ntau dua thiab muaj kev cuam tshuam tsawg dua, nws yog qhov tseem ceeb rau cov ntawv thov tseem ceeb uas cov ntaub ntawv ncaj ncees yog qhov tseem ceeb.
