Mugadziri wega wepasi rose we discrete MRAM chips, Everspin Technologies, anoenderera mberi nekuvandudza matekinoroji ekugadzira. Nhasi, Everspin uye GlobalFoundries kubatanidza 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, sero rimwe nerimwe rine rayo (conditionally) magnetic head. Iyo STT-MRAM ndangariro yakaitsiva, zvichibva pamhedzisiro yekufambisa nguva yekutenderera yeelectronic, inoshanda pamwe nemutengo wakaderera wesimba, sezvo ichiitika uchishandisa yakaderera mafungu mukunyora uye kuverenga modes.
Pakutanga, NXP yakagadzira MRAM yeEverspin pachirimwa chayo cheUS. Muna 2014, Everspin akapinda mumubatanidzwa neGlobalFoundries. Pamwe chete, vakatanga kugadzira discrete uye yakamisikidzwa MRAM (STT-MRAM) magadzirirwo ekugadzira vachishandisa mamwe epamberi ekugadzira maitiro.
Nekufamba kwenguva, GlobalFoundries yakatanga kugadzirwa kwe40-nm uye 28-nm STT-MRAM machipi (kuchipera nechigadzirwa chitsva, iyo 1-Gbit discrete STT-MRAM chip), uye yakagadzirira iyo 22FDX process tekinoroji yekubatanidza STT-MRAM arrays mu controller vachishandisa 22-nm process tekinoroji paFD-SOI wafers. Chibvumirano chitsva pakati peEverspin neGlobalFoundries chichatungamira mukuendeswa kweSTT-MRAM chip kugadzirwa kune 12-nm process tekinoroji.
MRAM ndangariro iri kusvika SRAM ndangariro maererano nekuita uye inogona kutsiva iyo mune controller yeInternet yezvinhu. Panguva imwecheteyo, haina-inoshanduka uye yakanyanya kupfeka-inodzivirira pane yakajairwa NAND ndangariro. Shanduko kuenda ku12-nm zviyero zvichawedzera kurekodha density yeMRAM, uye ichi ndicho chikuru dhizaini.
