Prague, January 7, 2014 - AbakwaSamsung, umholi womhlaba kwezobuchwepheshe benkumbulo nokukhiqiza, wethule eyokuqala I-8Gb inkumbulo yeselula dram s ukusetshenziswa kwamandla okuphansi kwe-LPDDR4 (amandla aphansi isilinganiso sedatha ephindwe kabili 4).
"Lesi sizukulwane esisha i-LPDDR4 DRAM sizofaka isandla kakhulu ekukhuleni ngokushesha kwemakethe yeselula ye-DRAM, maduze nje izoba nesabelo esikhulu kunazo zonke emakethe ye-DRAM.,” kusho u-Young-Hyun May, iPhini Likamongameli Omkhulu Webhizinisi Nokumaketha we-Memory Division ye-Samsung Electronics. "Sizolwela ukuhlala isinyathelo esisodwa ngaphambi kwabanye abakhiqizi futhi siqhubeke nokwethula i-DRAM yeselula yesimanje ukuze abakhiqizi bomhlaba bakwazi ukwethula amadivaysi eselula amasha ngesikhathi esifushane kakhulu.,” kwenezela u-Young-Hyun May.
Ngezici zayo ezinjengokuminyana kwenkumbulo ephezulu, ukusebenza okuphezulu nokusebenza kahle kwamandla, izinkumbulo zeselula ze-Samsung DRAM LPDDR4 zizokwenza abasebenzisi bokugcina bakwazi ukusebenzisa. ethuthukisiwe izicelo ngokushesha futhi bushelelezi futhi ujabulele ukulungiswa okuphezulu isibonisi ngokusetshenziswa kwebhethri okuncane.
Izinkumbulo ezintsha zeselula ze-Samsung DRAM LPDDR4 ezinomthamo we-8Gb ziyakhiqizwa Ubuchwepheshe bokukhiqiza be-20nm futhi inikeza umthamo ongu-1 GB ku-chip eyodwa, okwamanje okuyinani eliphakeme kakhulu lezinkumbulo ze-DRAM. Ngama-chips amane, ngalinye linomthamo ongu-8 Gb, ikesi elilodwa lizohlinzeka ngo-4 GB we-LPDDR4, izinga eliphezulu lokusebenza elitholakalayo.
Ngaphezu kwalokho, i-LPDDR4 isebenzisa i-low-voltage I-Logic Voltage Ephansi Enqanyuliwe (LVSTL) I/O interface, okwaklanywa i-Samsung i-JEDEC. Ama-chips amasha afinyelela isivinini sokudlulisa esingafika ku 3 Mbps, okuyijubane eliphindwe kabili lama-LPDDR3 DRAM akhiqizwe manje. Nokho, ngesikhathi esifanayo idla amandla acishe abe ngama-40%. ku-voltage engu-1,1 V.
Nge-chip entsha, i-Samsung ihlela ukugxila hhayi kuphela emakethe yeselula ye-premium, kufaka phakathi Ama-smartphones e-UHD ngesibonisi esikhulu, kodwa futhi sivuliwe amaphilisi a ama-notebooks ama-ultra-slim, enikeza isibonisi esiphakeme ngokuphindwe kane kunokulungiswa kwe-Full-HD, futhi futhi phezulu amasistimu enethiwekhi anamandla.
I-Samsung ingumthuthukisi oholayo wobuchwepheshe beselula be-DRAM futhi ingumholi wesabelo semakethe kuselula ye-DRAM ene-4Gb ne-6Gb LPDDR3. Le nkampani yaqala ukunikeza i-3GB LPDDR3 (6Gb) encane kakhulu nencane kakhulu ngoNovemba futhi yethula i-8Gb LPDDR4 DRAM entsha ngo-2014. I-chip ye-8Gb yeselula ye-DRAM izokhula ngokushesha kakhulu emakethe yamadivayisi eselula yesizukulwane esilandelayo isebenzisa ama-chips e-DRAM aphezulu.
