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 rugero runini. 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.
Itsinda ry’umunyeshuri wigishaga Liu Ming wo mu kigo cya Microelectronics ryashizeho kandi ryashyize mu bikorwa imbogamizi zihura nazo za hafnium zashyizwe mu bikorwa ku nshuro ya mbere ku isi hashingiwe ku mbuga nini yo guhuza ibikorwa bya hafnium bishingiye kuri ferroelektrike ya CMOS, hamwe na CMOS yuzuye. 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 Gusoma / Kwandika ukoresheje ECC-Ifashijwe na Data Refresh" ishingiye ku bisubizo kandi Offset-Canceled Sense Amplifier "yatoranijwe muri ISSCC 2023, kandi chip yatoranijwe mu nama ya ISSCC Demo kugirango yerekane Ji Y mu nama. umwanditsi 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.
