Ubwoko bushya bwa hafnium bushingiye kuri ferroelektrike yibikoresho byakozwe kandi byakozwe na Liu Ming, Umwarimu w’Ikigo cya Microelectronics, byerekanwe mu nama mpuzamahanga ya IEEE mpuzamahanga ikomeye (ISSCC) mu 2023, urwego rwo hejuru rwo guhuza ibizunguruka.
Imikorere-yimikorere myinshi yashyizwemo ububiko budahindagurika (eNVM) irakenewe cyane kuri chip ya SOC mubikoresho bya elegitoroniki byabaguzi, ibinyabiziga byigenga, kugenzura inganda nibikoresho bikoresha interineti yibintu.Ububiko bwa ferroelektrike (FeRAM) bufite ibyiza byo kwizerwa cyane, gukoresha ingufu zidasanzwe, no kwihuta cyane.Irakoreshwa cyane mubwinshi bwamakuru yandika mugihe nyacyo, gusoma amakuru kenshi no kwandika, gukoresha ingufu nke hamwe nibicuruzwa bya SoC / SiP.Ububiko bwa ferroelektrike bushingiye kubikoresho bya PZT bwageze ku musaruro rusange, ariko ibikoresho byabwo ntibishobora kubangikanywa n’ikoranabuhanga rya CMOS kandi biragoye kugabanuka, biganisha ku iterambere ry’imikorere gakondo ya ferroelektrike irabangamiwe cyane, kandi kwishyira hamwe bikenera inkunga y’umurongo utandukanye, bigoye kumenyekana. ku bunini.Miniaturabilité yububiko bushya bwa hafnium yibuka ferroelectric yibuka no guhuza hamwe nikoranabuhanga rya CMOS bituma iba ahantu h’ubushakashatsi harebwa abantu benshi muri za kaminuza ninganda.Hafnium ishingiye kuri ferroelectric yibuka yafashwe nkicyerekezo cyingenzi cyiterambere cyibisekuruza bizaza.Kugeza ubu, ubushakashatsi bwakozwe na hafnium bushingiye kuri ferroelectric yibuka buracyafite ibibazo nko kutizera kwingirakamaro bidahagije, kubura igishushanyo cya chip hamwe n’umuzunguruko wuzuye, ndetse no kugenzura imikorere ya chip, igabanya ikoreshwa ryayo muri eNVM.
Mu rwego rwo guhangana n’ibibazo byugarije ububiko bwa ferroelektrike ya hafnium yashyizwemo, itsinda ry’Umunyeshuri Liu Ming wo mu Ishuri Rikuru rya Microelectronics ryateguye kandi rishyira mu bikorwa imashini y’ibizamini bya megab-nini ya FeRAM ku nshuro ya mbere ku isi ishingiye ku mbuga nini yo kwishyira hamwe. ya hafnium ishingiye kuri ferroelectric yibuka ihuza na CMOS, kandi yarangije neza guhuza kwinshi kwinshi kwa HZO ferroelectric capacitor muri 130nm ya CMOS.Hatanzwe na ECC yandika ibizunguruka kugirango yumve ubushyuhe hamwe na amplifier yumvikanisha uburyo bwo kurandura burundu offset irasabwa, kandi 1012 cycle igihe kirekire na 7ns kwandika na 5ns yo gusoma biragerwaho, nizo nzego nziza zavuzwe kugeza ubu.
Urupapuro "9-Mb HZO rushingiye kuri Embedded FeRAM hamwe na 1012-Kwihangana Cycle na 5 / 7ns Soma / Andika ukoresheje ECC-Ifashijwe na Data Refresh" ishingiye kubisubizo kandi Offset-Canceled Sense Amplifier "yatoranijwe muri ISSCC 2023, kandi chip yatoranijwe mu isomo rya ISSCC Demo kugirango yerekanwe mu nama.Yang Jianguo niwe mwanditsi wambere wimpapuro, naho Liu Ming niwe mwanditsi uhuye.
Imirimo ijyanye nayo ishyigikiwe na Fondasiyo yubumenyi y’ubumenyi y’igihugu y’Ubushinwa, Gahunda y’ingenzi y’ubushakashatsi n’iterambere rya Minisiteri y’ubumenyi n’ikoranabuhanga, hamwe n’umushinga B w’icyiciro cya B w’ishuri ry’ubumenyi mu Bushinwa.
