Lub ntiaj teb tsuas yog tus tsim tawm ntawm kev sib cais magnetoresistive MRAM nco chips, Everspin Technologies, txuas ntxiv txhim kho cov thev naus laus zis ntau lawm. Niaj hnub no Everspin thiab GlobalFoundries ua ke los tsim cov thev naus laus zis rau kev tsim cov STT-MRAM microcircuits nrog 12 nm qauv thiab FinFET transistors.
Everspin muaj ntau dua 650 patents thiab daim ntawv thov cuam tshuam nrog MRAM nco. Qhov no yog lub cim xeeb, sau ntawv mus rau ib lub xovtooj ntawm tes uas zoo ib yam li sau cov ntaub ntawv rau lub phaj hlau nplaum ntawm lub hard disk. Tsuas yog nyob rau hauv cov ntaub ntawv ntawm microcircuits puas txhua lub xov tooj ntawm tes muaj nws tus kheej (txheej xwm) lub taub hau sib nqus. Lub cim xeeb STT-MRAM uas hloov nws, raws li lub zog hloov hluav taws xob hloov pauv, ua haujlwm nrog cov nqi hluav taws xob qis dua, vim nws siv qis qis hauv kev sau ntawv thiab nyeem ntawv.
Thaum pib, MRAM nco tau xaj los ntawm Everspin tau tsim los ntawm NXP ntawm nws cov nroj tsuag hauv Tebchaws Meskas. Hauv 2014, Everspin tau nkag mus rau hauv kev pom zoo ua haujlwm nrog GlobalFoundries. Ua ke, lawv pib tsim kev sib cais thiab kos MRAM (STT-MRAM) cov txheej txheem tsim khoom siv cov txheej txheem tsim khoom ntau dua.
Lub sijhawm dhau los, cov chaw GlobalFoundries tau pib tsim cov 40-nm thiab 28-nm STT-MRAM chips (kawg nrog cov khoom tshiab - 1-Gbit discrete STT-MRAM nti), thiab tseem tau npaj 22FDX txheej txheem thev naus laus zis rau kev sib koom ua ke STT- MRAM arrays rau hauv cov tswj siv 22-nm nm txheej txheem thev naus laus zis ntawm FD-SOI wafers. Daim ntawv cog lus tshiab ntawm Everspin thiab GlobalFoundries yuav ua rau kev hloov pauv ntawm kev tsim STT-MRAM chips rau 12-nm txheej txheem thev naus laus zis.
MRAM nco tau nce mus txog qhov ua tau zoo ntawm SRAM nco thiab tuaj yeem hloov pauv hauv cov tswj hwm rau Is Taws Nem ntawm Yam. Nyob rau tib lub sijhawm, nws tsis hloov pauv thiab tiv taus hnav ntau dua li cov qauv NAND nco. Kev hloov mus rau 12 nm cov qauv yuav ua rau kom cov ntaub ntawv ceev ceev ntawm MRAM, thiab qhov no yog nws qhov teeb meem tseem ceeb.
