Imemori ye-DDR5 iyinkanyezi yesandulela se teknoloji RAM, ekunenxa kwezindawo zokusebenza nezinhambiliyo endala kuzo zonke izinhlelo zokusebenza zamadoda. Lesi stande lomemori olukhulu lisebenza ngamagigaba amakhulu ngokuhamba kwalo, angena emva kwamagigaba angu-4800 MHz noma ukuba ngu-8400 MHz. Lo teknoloji luyindlela yokulungisa amaphoyinti okwenza ikhowudi ye-ECC kunye nokuthuthukiswa kwegolide lemvula ngokudibanisa i-PMIC (ingxotho yokuvela). I-DDR5 idityanisa kabili i-bandwidth kunye ne-engxenye ye-DDR4, ekunena amagigaba angu-64 per die akuvumela ukuthi kube ngu-128GB. I-architecture inezilayidi ezimbini ezingenasipho esinye sokulingana nezinhlamvu ezingu-32-bit ngasinye, ekunakho ukuthi kube lula ukusebenza ngokuphelelwe nezindawo zokusebenza ngokuphelelwe. Ngekweyona mvula yokusebenza engu-1.1V, i-DDR5 ikunena inkathi yokuthatha amandla ngelixa yenqokolela kakhulu. Lo teknoloji lwenza futhi ukuthuthuka kwe-burst length kunye nokuthuthuka kwamaphepha, okwenzela ukuthi kube lula ukufinyelela memori kunye nokubusa ukugcina. Lezi zinto eziphambene nezizathu zenze i-DDR5 isetshenziswa kakhulu kuma-aplikesheni athintana ne-data, ukusebenza okuphezulu, ukuvela kwabantu, kunye nezinhlelo zokuthengisa eziphambene nezinye.

Imemori ye-DDR5 inika amaphethelo amaningi okwenza kube khona ukukhetha okuphezulu kwezimali zokusebenza ngoku. Okokuqala, ukunyuka ngokubangelwa kwesikhati nokugcinwa kwebandwidth kukuvumela ukuguqula amadatha ngokomkhiyambo, okwenza isistimu iyapinda ngokushesha futhi ibe yindlela yokulayisha. Isikhati esiphakathi esiphezulu se-4800 MHz, ngokulinganisa ne-DDR4 engu-3200 MHz, kuyenza ukusebenza ngokushesha ngokubangelwa kuzindleko eziningi. Ukulethana ngemali nge-PIC esifakwe khona akuthuli kuphela ukusetshenziswa komoya kodwa nokuba yisistimu enezikhundla eziphakade. Ubude bokudluliselana obuphandeyo be-16 bavumela ukufinyelela amadatha ngendlela efanele, okungukithi kakhulu kuzo zinhlelo zokusebenza ezidla amadatha amakhulu. Imikhwako emathiselene nemathikasi yokuhlinzeka ngempumelelo iyagcina integrity yedatha futhi kusisise isistimu, okungukithi kakhulu kuzo zinhlelo zokusebenza ezibalweni nezidingekayo. Inkxenye yokugcinwa ngokuphezulu ikuvumela ukucwangcwa okuningi kwegigaba, okungukithi kakhulu ukwengeza izinhlelo ukuze kuthatheke njalo xa izidingo zohlelo lokusebenza ziphelisa. Uhlobo lwezimbali ezimbili ngasinye igama elilodwa lifinyelela imemori ngendlela efanele, okungukithi kakhulu kuzo zimo ezijwayelekile nezokusebenza ngokushesha. Ishukela sokusebenza esingaphansi se-1.1V sithintela ukuthi sisetshenziswe ngokuncane komoya futhi sihlale ngaphansi, okwenza i-DDR5 kube yinkukhu yokukhetha. Lezi ziboniso zombilo zenza ukuba kube nenjini yokuqonda, yeqiniso futhi yefanele, okungukithi kakhulu kuzo zinhlelo zokusebenza ezidingekayo njengokudala uhlelo, ukusebenza kwezinhlangano, futhi ukudlala izindanda ezephezulu.

Isispeed fokuthu nebandwidth ephumelelayo

Imemori ye-DDR5 iyisetha isitimela esisha lokushisa nokusebenza kwezinto, kuyachaza ukuguqula okukhulu ememorini. Le ndawo yokuqala yokwenza le nto nguqulelo yayo edlule ngokuthi i-frequency ekuqaleni ibe 4800 MHz, okuhamba ngapandle kwezinhloso zezinye izinhloso zangaphambili. Le nkinobodla yokushisa iyancediswa ngendawo enkulu yokugcina amadatha ngamanye amakhasi, okungenjalo kubonakala ngokuphindelwa kabili ikhono lokusebenza lenyuka ngalunye ulayini. Kukusebenyiswa kwesibonelo sokuthi le nkinobodla inobude bama-16-bit, okungaphezu kwama-8-bit ase DDR4, kuvumela ukuth transfer amadatha kahle futhi kusetshenziselwe ikhono elikhona. Le mpumelelo enhle kakhulu ibonakala kuzo zindlela eziningi zokusebenzela apho kudingeka ukuth sebenzelwe amadatha amaningi ngokushesha nokusebenza ngokulula. Ikhiye lokusebenza kwekhono elikhona alaleli kuphela ukushisa kwokuth transfer amadatha kodwa nohlelo lwesistimu lwenzeke ngokushesha, linakeke amathenjelwano futhi livinjelwe ukusebenza ngokulula kuzo zimo ezidingekayo.

Ukuphatha Amandla Nefficiency

Enye yeziqakwana eziphambene ne-DDR5 yile ndlela yokupheya amandla okusebenza, esetshenziswa kwi-PMIC (Power Management IC). Le ndlela entsha iyathuma ukulawulwa kwemivolthi kuselengoma yemother kumodi wokugcinwa. Lokhu kwenza ukuthola kwamandla kube nephepha futhi kube nemifiswano eminingi. Imivolthi encane (1.1V), ngokuhlanganisa nezothekwano zokupheya amandla, kunika amahasha aphezulu asebenzayo ngeke athinte isebenza. I-PMIC nakunikeza ukulawulwa kwevholthi neyokuvela kwamandla, okwenza ukusebenza kube mizuzwana ngokushintshashintsha kwegama lokusebenza. Le ndlela yokupheya amandla ayenza ukuthi amandla athathwa kube ncane futhi akunike amandla amakhane, okungenxa koku kube yimaliphi kanye nokudala kwezinhlelo. Le mahasha aphambene nezindleko zamandla angenako ukungcola kwezinhlelo ezinamandla okuphambene nezindleko ezinciyile.

Ukunakekwa Okuhlelwe Nezibonelo Sokulungisa Imposo

Imemori ye-DDR5 iyavumela ukusebenza kwezimposiso zokulungisa iphutha okuhlelwa kakhulu ubuninzi bethenjelweni nokuvikela isistimu. Ukusebenziswa kwe-ECC (Error Correction Code) kwi-chip ikhombisa uhlelo oluphimileyo kusendvabhakweni lelipha lapho imiphumela ivikwa, nokuwephesa amandla ngokugcinwa kwebethenjelwe. Le ndawo inqaba kakhulu ezingeni leprofeshele apho ubuncikezelwe bethenjelwe buqukethwe. Ubunamileyo obuhlelwanga buyasekelwe hlaselwa ukulethwa kwamanje okuhlelwa kakhulu okunciphisa ukuba kubonakala phakathi kwemisebenzo encane. Isiphindaphindle yale mephame yenziwa isistimu sememori esibonakalayo kudinga kahle kuzindlela zomsebenzi wokuxhumana ngamanje. Imiphumela yokuhlola iphutha eyenhanyiswe ihlela ukuncipiswa kohlukahluka kwezinhlelo futhi ethintele ukuvikela isistimu ngokudla. Le mikhumbi elihleliyo yenza i-DDR5 ibe yisicelo esifanelekileyo ezinyangeni ezilula kakhulu apho izikhathi zokushutela isistimu kudinga kancishwe.
