Wopanga yekha padziko lonse lapansi wa discrete magnetoresistive MRAM memory chips, Everspin Technologies, akupitiliza kukonza ukadaulo wopanga. Lero Everspin ndi GlobalFoundries pamodzi kuti apange luso lopanga ma microcircuits a STT-MRAM okhala ndi 12 nm miyezo ndi FinFET transistors.
Everspin ili ndi ma patent opitilira 650 ndi ntchito zokhudzana ndi kukumbukira kwa MRAM. Uku ndiko kukumbukira, kulembera ku selo yomwe ili yofanana ndi kulemba chidziwitso ku magnetic plate ya hard disk. Pokhapokha pa ma microcircuits omwe selo lililonse limakhala ndi mutu wake wa maginito (moyenera). Chikumbutso cha STT-MRAM chomwe chinalowa m'malo mwake, kutengera mphamvu ya electron spin momentum transfer effect, chimagwira ntchito ngakhale mtengo wotsika wa mphamvu, chifukwa chimagwiritsa ntchito mafunde otsika polemba ndi kuwerenga.
Poyambirira, kukumbukira kwa MRAM kolamulidwa ndi Everspin kudapangidwa ndi NXP pafakitale yake ku USA. Mu 2014, Everspin adalowa mgwirizano wantchito ndi GlobalFoundries. Pamodzi, adayamba kupanga njira zopangira zida za MRAM (STT-MRAM) pogwiritsa ntchito njira zapamwamba kwambiri.
Popita nthawi, malo a GlobalFoundries adayambitsa kupanga tchipisi ta 40-nm ndi 28-nm STT-MRAM (kutha ndi chinthu chatsopano - chip 1-Gbit discrete STT-MRAM), komanso adakonza ukadaulo wa 22FDX wophatikizira STT- MRAM imapanga ma controller pogwiritsa ntchito teknoloji ya 22-nm nm pa FD-SOI wafers. Mgwirizano watsopano pakati pa Everspin ndi GlobalFoundries udzatsogolera kusamutsa kwa tchipisi ta STT-MRAM kupita kuukadaulo wa 12-nm.
Memory ya MRAM ikuyandikira kugwira ntchito kwa kukumbukira kwa SRAM ndipo imatha kuyisintha kukhala owongolera pa intaneti ya Zinthu. Nthawi yomweyo, imakhala yosasunthika komanso yosamva kuvala kuposa kukumbukira wamba kwa NAND. Kusintha kwa miyezo ya 12 nm kudzawonjezera kujambula kwa MRAM, ndipo ichi ndiye cholepheretsa chake chachikulu.
