imemori ye-ddr4 yamaseva

Imemori ye-DDR4 yezimvume iyinkqubo enkulu kakhulu yokuvuselela ikhowudi yesicelo, ekunikeza ukuphepha nokuthula okuningi kuzindlela zokusebenzisa izisekelo. Le memori yedolophu ledata le-generation ephindwe kabili ingasebenze ngamagigaba amaceke ngaphansi kokusebenza kwazo zingxenye ezidlule. Ngezimali ezingaphansi koku-1.2V futhi ubukhawulezi bokuhlolwa kwe-data benza ku-2133 MT/s, imemori ye-DDR4 yenziwa ngendlela yokusebenza ngokukhulu kuzindlela zokusebenza ezihlengahlengi. Lo teknoloji inemibono engenhla yokulungisa impawu, eyaziwa ngokuthi Error-Checking and Correction (ECC), okuyinkinga enkulu ukuqinisekisa ukuthi idatha ayishiwo kuzindlela zokusebenza ezibalweni. Imimodi ye-DDR4 zenikwa amathola amaningi, okungenani phakathi kwe-8GB kuya ku-256GB ngalinye, ukunika amandla wokuthola amathola alandelanayo ngokwesicelo esithile. Isakhiwo se-DDR4 sinemigidi yokuthuthwa kwegama elingeni ngenxa yekhothazwa kahle kwezinhlelo nangaphezulu yokuphepha kwamanzi, ukunikeza ukusebenza ngendlela noma lapho kunezinto ezikhulu. Le mimodi yenziwa ngendlela yokuthola isisayo esisha sezimvume, ukunikeza indawo efunekayo yokusebenza ngokushelane, ukuphathwa kwezinhlanzi, ukusebenzisa i-cloud, nezinye izindlela zokusebenza eziphezulu.

Imemori ye-DDR4 yezinhlayiya ikhona amanye amaphetho athintekayo okwenza kube yona indlela elikhethwayo kulokhu kwezinhlayiya zomkhiqizo osha. Okokuqala, ukunciphisa imali yokusebenza ngokuthuthukile kubangela ukuncipiswa komkhawulo wevimba, ngeke kungaphezu kwe-20% ngaphansi kuka-DDR3. Iindlela zokulayisha idatha, eziquka phakathi kwe-2133 MT/s kanye ne-3200 MT/s, zenzelela ukusebenziswa ngokushesha kwamadatha amakhulu futhi ukuthuthukiswa komsindo wokusebenza. Le bandwith ephakeme kangaka iyisiza ekuzimeleni izimo ezinjenge-virtualization lapho amasevisi amaningi ayivumelela imali. Imali yesikweletu seDDR4 server memory enobungozi obuphakeme bethinta ukuthi ibe nemibandela yokuhlinzela nokwakisa idatha, ukunciphisa isikhathi esingakanani futhi sikhombise ukugcinwa kwedatha. Ukunikezwa kwe-signal integrity kanye ne-interference electrical ephansi kungenzeka ukusebenza okudavulayo kusistimu, noma lapho kuzinhlayiya eziningi. Imoduli ye-density ephakeme kuka-DDR4 zenzelela ukuba inani lememori lisibe libe ngaphezulu kuzinhlayiya, liyisiza ukuthuthukiswa kokuthenga kwezinhlobo zedatha ezininzi futhi zenzelela ukuba kube nenani elikhulu lamavhumahvuma ku-server ngalinye. Ukuhlolwa kweteknoloji kuyenza ukuthi kune-dissipation yokunqelwa, okungenzeka ukuthuthukiswa komsindo futhi ukuba yilapho kwezimpawu. Ngokudla, imoduli ye-DDR4 server memory ingaba nezinto ezinzile ezijwayele ukusebenzisa ukulandelana nokulungisa, ukuqinisekisa ukuthi umsindo ongcono wenqizihlo lapho kusebenzwa. Ukuthuthukiswa kweDDR4 memory systems kuyenze ukuthi abasebenzisi bakwazi ukuvuselela uhlelo lwabo lokusebenza ukuze liqhutshelwe amathiphu athola ngaphandle kokudinga ukuthi uhlelo wonke ubeniwe.

Ukuphakama nokusebenza okuningi

I-DDR4 inhlaka lendliyiselweyo inciphisa ngokukhulu ukulethwa kwemisebenzi ngokuthiwa yonakele isayithi sakhiwo ne-increase yeziphumo zokulandelana. Lo technology isekela imisholo yesikhatiwe eziza kusukela ku-2133 MT/s fokwenzelela ku-3200 MT/s, okubonisa ukuthayelela okukhulu ngaplandeleni kwegenereshini ezedlule. Lokhu kumele kuhlukaniswa okuningi kuholela ekucatheni kwezinhloko zendliloselweyo nekuwakheka kokusebenza ngokunye. Isebenzo esiphezulu sikhuthazwa ngokuchanekile kwezindlela ezinhlanu zokuxhumana, njenge-signal integrity enembile, nezinhlanu zokushintshana nokuhlelwa kwebandla. Lezi zinto ezinembile zenze i-zinhlotsha zindlethwa izinto eziningi zedatha ngendlela efanele, lokhu kuyindlela engcono yokusebenzela njengokuvavanya okulinganiselwe, ukusebenzisa amacala athile, nezinjini zokugcinwa kwamafomu amakhulu.

Ukulungisa Imposiso Fane Nokubambisana

Ukusebenzisa imikemele yokulungisa impawu engqongqweni yememori yamaphakheji DDR4 iyinkanyezi esenza ngokubaluleka ekugcineni ubumfihlakuse. Inqanawa ye-Error-Checking and Correction (ECC) isetshenziswa kakhulu emmemorini, ikhuthaza ukwazi nokulungisa noma impawu enye noma amaningi ngokushesha. Le ngxenzo iyinjani kakhulu emazingeni yamaphakheji lapho ubukhona betha kudingeka. Imemori yenqatophakheji inezinhlobo ezifakiweyo zokwaziya nekulungisa impawu, uyisela ukuthi izikhathi ezibalulekile ziqhubekise ngaphandle kokuphazamiseka noma uma kube nenqeto yememori. Lokhu kungenzeka ukuthuthukiswa kokuqhubekayo komoya, ukuncipiswa kwamaminithi angatholiwe, nokuvikelwa ngempela ketha ledata ebaluleke kakhulu emazingeni yasekhaya.

Ukusebenza Kwamandla Nokuphatha Intampu

Imemori yamaphondo ye-DDR4 isetile amastandadu okuphucula kwezinga eliphezulu le-ukusebenza ngokushesha kwezinga lokusetshenziswa kwamandla nokuphatha ukushisa. Isebenza kuzinga olungu-1.2V ngokulingana ne-1.5V ebalulekileyo yi-DDR3. Ukuhlelwa kwalokusetshenziswa kwamandla kubangela ukunciphisa okuphezulu kwamandla, ngakumbi emaphondweni amakhulu ezimalayezo zedatha. Ukusebenza okuphuculiwe kwezimalayezo kunikezwa inkqubo yokuphatha ukushisa okunconywa futhi okuhlobo lokuqinisekisa ukuba kunesitayela esiyisodwa sokusebenza phakathi kwezindleko ezinkulu. Le memori inamathini amanqaku okuphatha ukushisa nezinselelo ezinhle zokuphatha ukushisa okusebenzisa izinko ezohlelwa zedatha ekugcineni ukungena eshiseni futhi ukuqinisekisa ukusebenza okuphephile. Lezi zinto ezinhle zokuphatha ukushisa zikusiza ukulawula ukuphila kwezinto kanye nokunciphisa izindleko zokushisa emaphondweni.
