Raws li IBM cov lus tshaj tawm, lub tuam txhab tsim magnetoresistive MRAM nco hauv xyoo 1996. Txoj kev loj hlob tau tshwm sim tom qab kawm cov txheej txheem nyias-zaj duab xis rau cov hlau nplaum sib nqus thiab lub taub hau sib nqus ntawm cov hard drive. Cov nyhuv ntawm magnetic tunnel junctions nrhiav tau los ntawm lub tuam txhab engineers prompted lub tswv yim ntawm kev siv lub phenomenon los npaj semiconductor nco hlwb. Thaum pib, IBM tsim MRAM nco ua ke nrog Motorola. Tom qab ntawd cov ntawv tso cai raug muag rau Micron, Toshiba, TDK, Infineon thiab lwm lub tuam txhab. Vim li cas qhov kev mus ncig no rau hauv keeb kwm? Nws tau muab tawm tias Seagate, yog ib qho ntawm ob lub chaw tsim khoom lag luam uas tseem tshuav nyob hauv lub ntiaj teb, muaj patents ntawm MRAM cov thev naus laus zis ntau lawm.
Nag hmo Seagate , hais tias nws muaj kev pom zoo hla kev tso cai rau patent sib koom thiab kev tso cai ntawm nws thiab Everspin Technologies. Nws raug liam tias Seagate thiab Everspin tau siv sijhawm ntau xyoo rau kev tshawb fawb thiab kev txhim kho uas yuav muaj txiaj ntsig zoo rau txhua tus neeg tawm tsam. Yog li, Seagate pauv mus rau Everspin txoj cai los siv nws tus kheej kev txhim kho hauv thaj chaw ntawm MRAM, thiab Everspin tau tso cai rau Seagate siv nws cov thev naus laus zis hauv kev tsim cov hlau nplaum taub hau raws li Tunneling Magneto Resistance (TMR) cov nyhuv.
Hauv qhov tseem ceeb, Seagate thiab Everspin tau ua raws li lub hauv paus patent uas tuaj yeem pab lawv txhua tus nce qib hauv lawv cov haujlwm. Everspin cov ntawv tso cai yuav pab Seagate txhim kho lub taub hau sib nqus rau cov tsav nyuaj, thiab Seagate cov ntawv tso cai yuav tsis cuam tshuam nrog Everspin txoj kev loj hlob thiab tsim MRAM. Thaum Lub Yim Hli, Everspin tsuas yog loj zus tau tej cov 1-Gbit STT-MRAM chips thiab tau daim ntawv tso cai tsis txaus siab nrog Seagate tsuas yuav ua mob rau qhov no tseem tsis zoo tsim cheeb tsam ntawm semiconductor nco ntau lawm.
