A cewar sanarwar hukuma ta IBM, kamfanin ya ƙirƙira ƙwaƙwalwar ajiyar MRAM na magnetoresistive a cikin 1996. Ci gaban ya bayyana bayan nazarin tsarin sirara-fim don faranti na maganadisu da kawuna na faifai. Tasirin mahaɗar rami na maganadisu da injiniyoyin kamfanin suka gano ya haifar da tunanin yin amfani da abin al'ajabi don tsara ƙwayoyin ƙwaƙwalwar ƙwaƙwalwa na semiconductor. Da farko, IBM ya haɓaka ƙwaƙwalwar MRAM tare da Motorola. Sannan an sayar da lasisin ga Micron, Toshiba, TDK, Infineon da sauran kamfanoni masu yawa. Me yasa wannan balaguron cikin tarihi? Ya bayyana cewa Seagate, ɗaya daga cikin masana'antun rumbun kwamfyuta guda biyu da suka rage a duniya, yana da manyan haƙƙin mallaka akan fasahar samar da MRAM.
Jiya Seagate , cewa yana da babbar yarjejeniya ta lasisi don raba haƙƙin mallaka da lasisi tsakaninta da Everspin Technologies. An yi zargin cewa Seagate da Everspin sun shafe shekaru a kan bincike da ci gaba da za su yi matukar amfani ga kowane bangare na gaba. Don haka, Seagate ya koma Everspin haƙƙin yin amfani da abubuwan ci gaba nasa a fagen MRAM, kuma Everspin ya ƙyale Seagate yayi amfani da fasaharsa wajen samar da kawuna na maganadisu dangane da tasirin Tunneling Magneto Resistance (TMR).
A zahiri, Seagate da Everspin sun daidaita tushen haƙƙin mallaka wanda zai iya taimaka wa kowannensu ya ci gaba a fannonin su. Sharuɗɗan lasisin Everspin za su taimaka wa Seagate haɓaka kawuna na maganadisu don tukwici masu wuya, kuma lasisin Seagate ba zai tsoma baki tare da ci gaban Everspin da samar da MRAM ba. A watan Agusta, Everspin kawai yawan samar da kwakwalwan kwamfuta na 1-Gbit STT-MRAM da yuwuwar takaddamar lasisi tare da Seagate zai cutar da wannan yanki mara kyau na samar da ƙwaƙwalwar semiconductor.
