Mugadziri wega wepasi rose we discrete magnetoresistive MRAM memory chips, Everspin Technologies, inoenderera mberi nekuvandudza matekinoroji ekugadzira. Nhasi Everspin uye GlobalFoundries pamwe chete kugadzira tekinoroji yekugadzira STT-MRAM microcircuits ine 12 nm zviyero uye FinFET transistors.
Everspin ine pamusoro pe650 patents uye maapplication ane chekuita neMRAM ndangariro. Ichi chiyeuchidzo, kunyora kune sero iyo yakafanana nekunyora ruzivo kune magnetic plate ye hard disk. Chete munyaya ye microcircuits iyo sero rimwe nerimwe rine rayo (conditionally) magnetic head. Iyo STT-MRAM ndangariro yakaitsiva, zvichibva pane erekitironi spin kukurumidza kutamisa mhedzisiro, inoshanda nechero yakaderera mutengo wesimba, sezvo ichishandisa yakaderera ikozvino mukunyora uye kuverenga modes.
Pakutanga, ndangariro yeMRAM yakarairwa naEverspin yakagadzirwa neNXP pachirimwa chayo muUSA. Muna 2014, Everspin akapinda muchibvumirano chebasa rakabatana neGlobalFoundries. Pamwe chete, vakatanga kugadzira discrete uye yakamisikidzwa MRAM (STT-MRAM) magadzirirwo ekugadzira vachishandisa mamwe epamberi ekugadzira maitiro.
Nekufamba kwenguva, zvivakwa zveGlobalFoundries zvakatangisa kugadzirwa kwe40-nm uye 28-nm STT-MRAM machipisi (achipera nechigadzirwa chitsva - 1-Gbit discrete STT-MRAM chip), uye zvakare akagadzirira 22FDX process tekinoroji yekubatanidza STT- MRAM inoronga kuita vatongi vachishandisa 22-nm nm process tekinoroji paFD-SOI wafers. Chibvumirano chitsva pakati peEverspin neGlobalFoundries chichatungamira mukufambiswa kwekugadzirwa kweSTT-MRAM machipisi kune 12-nm process tekinoroji.
MRAM ndangariro iri kusvika pakuita kweSRAM ndangariro uye inogona kutsiva iyo mune controller yeInternet yezvinhu. Panguva imwecheteyo, haina-inovhurika uye inopokana nekupfeka kupfuura yakajairwa NAND ndangariro. Shanduko kuenda ku12 nm zviyero zvichawedzera kurekodha density yeMRAM, uye ichi ndicho chikuru dhizaini.
