I te 1 o Hūrae, e ai ki ngā mōhiohio mai i te hui whakahaere o Samsung, i whakapā mai te tino hangarau o Samsung Electronics me te upoko o tōna Institute Rangahau Semiconductor i ngā whakawhitinga hou i runga i ngā hangarau pūngao kāwai e rua i te hui tūturu mō te rōpū Rongoā taputapu o te kamupene. I kapi ngā whakahoutanga i te whakarei-ai o te HBM4E nō te A.I. me te tukanga DRAM e te whitu 10nm e mōhiotia ana hei D1d.
E pā ana ki te whakawhanaketanga o HBM4E, ka mea te pūmana kua hiki te taumata whakamātautau pono o te hua ki runga i te 70%. I raro i ngā paerewa ahumahi, ko te hanganga 80% rānei te kūrae e pā ana ki te whakawhānuitanga pūnaha me te whakaputa nui nō nāianei. I runga i te wāhanga hua o nāianei, kei te noho anō te HBM4E i roto i te whakamātautau pono me te pokanga tauira, kāore anō i ekengia te pikinga whakaputa nui. E titiro ana ngā kaipōti supply-chain ki te hanga atu i runga i te 70% hei tohu whai take, e tohu ana kei te uru te mahi ki te mea kāore he āwangawanga, me te tatari ki te whakatairanga ake i te hoko.
E whakaatu ana ngā mōhiohio rōpū i te pānuitanga o ngā hua e mōhiotia ana kua tiimata a Samsung ki te tuku i ngā momo HBM4 tuatahi i te Hui-tanguru e pā ana ki tēnei tau. I te 29 o Mei, i whakaputahia e te kamupene ngā whakamārama hangarau katoa mo tana 12-layer HBM4E, ā, i timata ki te tuku raupapa tauira engineering ki ngā kaihoko chip AI whakataetae o te ao. Ko te whakatakotoranga o ngā whakatipu hua e rua ka tino kitea ngā rerekētanga. Kua whakamaheretia te HBM4 hei tautoko i ngā pūtau accelerator chip AI Vera Rubin a Nvidia e whakamaheretia ana mo te whakaputanga i te haurua tuarua o te tau, i te mea kei roto i te HBM4E whakahou i te pūnaha pūtea kei te whakamaheretia ki ngā taputapu rorohiko Ultra Vera Rubin mai i Nvidia i te tau e tū mai ana. Kua hangaia te 12-layer HBM4E a Samsung e whakamahi ana i ana tukanga DRAM e te ono 1c. E tuku ana i te tere pin taketake o 14 Gbps, ka taea te whakakoi ki runga i te 16 Gbps, me ngā whakapainga i te whakawhānuitanga, te whakaritenga pāmahana me te pai o te kōwhiringa pūngao i te taha o HBM4. Kua hangaia te hua mō ngā mahi rorohiko e teitei ake, me ngā whakatipuranga mō ngā taupōro nui, tae noa ki ngā pokanga raraunga teitei.
I te hui tūturu kotahi anō, nā ngā kaiwhakahaere o Samsung i whakahou te pānui e pā ana ki te whakawhanaketanga o te tukanga DRAM e te whitu o te kamupene. Ko te tukanga DRAM e te whitu 10nm, e mōhiotia ana ko D1d, e tirohia ana ki roto i te kamupene hei puta mā te kawe ki ngā hangarau whakataetae e ngā hoa ahumahi. Kua whakaritea e Samsung he tohu whakawhanaketanga mārama, e hiahia ana ki te whakaoti i te whakaaetanga whakaputa, ko te PRA, i te Whiringa-a-rangi 2026. Ko te whakaaetanga PRA he whakaritenga matua mo te neke i te tukanga DRAM mai i te R&D ki te whakarite whakaputa nui. I te wa e whakaaetia ana, ka timata te kamupene ki te whakauru i ngā taputapu nui, te whakapai i ngā pānga pokanga rākau me ngā pokanga whakamatautau nui.
E ai ki ngā mōhiohio e wātea ana, ko D1d te pokanga DRAM e te whitu e whakamaheretia ana e Samsung, me te rārangi whanui i te 10nm ki te 11nm. I te taha ki te tukanga DRAM eono e pā ana ki nāianei, ko te D1d ka whakawhānui ake i te hoki me te whakamahi i tētahi hanga cell hou i te taha o te rārangi transistor GAAFET e tautoko ana. E tumanako ana te tukanga ki te whakapai ake i te whānuitanga te nama iti i ia whakarewa me te painga pūngao, ā, ka noho hei hangarau tei runga te pūngao mō te rārangi tutu o te HBM5 e teitei ake o Samsung.
