Wahi a ka ʻōlelo kūhelu a IBM, ua hana ka hui i ka hoʻomanaʻo MRAM magnetoresistive ma 1996. Ua ʻike ʻia ka hoʻomohala ʻana ma hope o ke aʻo ʻana i nā hale kiʻiʻoniʻoni ʻoniʻoni no nā papa magnetic a me nā poʻo magnetic o nā paʻakikī paʻakikī. ʻO ka hopena o nā junction tunnel magnetic i ʻike ʻia e nā ʻenekini o ka ʻoihana i hoʻoikaika i ka manaʻo o ka hoʻohana ʻana i ka hanana e hoʻonohonoho i nā cell memory semiconductor. I ka hoʻomaka ʻana, ua hoʻomohala ʻo IBM i ka hoʻomanaʻo MRAM me Motorola. A laila ua kūʻai ʻia nā laikini iā Micron, Toshiba, TDK, Infineon a me nā hui ʻē aʻe. No ke aha kēia huakaʻi i ka mōʻaukala? Ua ʻike ʻia ʻo Seagate, kekahi o nā mea hana paʻakikī ʻelua i koe i ka honua, he nui nā patent ma nā ʻenehana hana MRAM.
I nehinei Seagate , i loaʻa iā ia kahi ʻaelike laikini keʻa nui no ka kaʻana like ʻana a me ka laikini ʻana ma waena o ia a me Everspin Technologies. Ua ʻōlelo ʻia ua hoʻolilo ʻo Seagate lāua ʻo Everspin i mau makahiki ma ka noiʻi a me ka hoʻomohala ʻana i mea e pono ai kēlā me kēia ʻaoʻao kūʻē. No laila, ua hoʻololi ʻo Seagate iā Everspin i nā kuleana e hoʻohana i kāna mau hoʻomohala ponoʻī ma ke kahua o MRAM, a ua ʻae ʻo Everspin iā Seagate e hoʻohana i kāna mau ʻenehana i ka hana ʻana i nā poʻo magnetic e pili ana i ka hopena Tunneling Magneto Resistance (TMR).
ʻO ke kumu, ua hoʻohālikelike ʻo Seagate a me Everspin i kahi waihona patent e hiki ke kōkua i kēlā me kēia o lākou e holomua i kā lākou mau kula. E kōkua nā laikini o Everspin iā Seagate e hoʻomaikaʻi i nā poʻo magnetic no ka paʻakikī, a ʻaʻole e hoʻopilikia nā laikini o Seagate i ka hoʻomohala ʻana a me ka hana ʻana o MRAM a Everspin. I ʻAukake, ʻo Everspin wale nō ʻO ka hana nui o 1-Gbit STT-MRAM chips a me nā hoʻopaʻapaʻa laikini hiki me Seagate e hōʻeha wale i kēia wahi i kūkulu maikaʻi ʻole ʻia o ka hana hoʻomanaʻo semiconductor.
