Everspin na GlobalFoundries agbatịla nkwekọrịta mmepe MRAM ha na teknụzụ usoro 12nm

Naanị onye nrụpụta ụwa nke magnetoresistive MRAM ebe nchekwa ibe, Everspin Teknụzụ, na-aga n'ihu na-akwalite teknụzụ mmepụta. Taa Everspin na GlobalFoundries ekweta ọnụ iji zụlite teknụzụ maka mmepụta nke STT-MRAM microcircuits nwere ụkpụrụ 12 nm na FinFET transistor.

Everspin nwere ihe karịrị 650 patent na ngwa metụtara ebe nchekwa MRAM. Nke a bụ ebe nchekwa, idegara otu cell nke yiri ịde ozi na efere magnetik nke diski ike. Naanị n'ihe banyere microcircuits ka cell ọ bụla nwere isi magnetik nke ya (na ọnọdụ). Ebe nchekwa STT-MRAM nke nọchiri ya, dabere na mmetụta mbufe ọkụ nke eletrọn, na-arụ ọrụ na ọnụ ahịa ume dị ala, ebe ọ na-eji obere mmiri na-ede ma na-agụ ụdịdị.

Na mbu, NXP mebere ebe nchekwa MRAM nke Everspin nyere n'osisi ya na USA. Na 2014, Everspin banyere na GlobalFoundries na nkwekọrịta ọrụ nkwonkwo. N'otu aka, ha malitere ịmalite usoro nrụpụta pụrụ iche na agbakwunyere MRAM (STT-MRAM) site na iji usoro nrụpụta dị elu karịa.

Ka oge na-aga, ụlọ ọrụ GlobalFoundries malitere mmepụta nke 40-nm na 28-nm STT-MRAM ibe (na-ejedebe na ngwaahịa ọhụrụ - mgbawa 1-Gbit discrete STT-MRAM), ma kwadokwara teknụzụ usoro 22FDX maka ijikọ STT- MRAM na-eji teknụzụ usoro 22-nm nm n'ime ndị njikwa na FD-SOI wafers. Nkwekọrịta ọhụrụ dị n'etiti Everspin na GlobalFoundries ga-eduga na mbufe mmepụta nke STT-MRAM ibe na teknụzụ usoro 12-nm.

Ebe nchekwa MRAM na-eru nso ịrụ ọrụ nke ebe nchekwa SRAM ma nwee ike dochie ya na njikwa maka ịntanetị nke ihe. N'otu oge ahụ, ọ na-adịghị agbanwe agbanwe na ọtụtụ ihe na-eguzogide iyi karịa ebe nchekwa NAND. Ntughari na ụkpụrụ 12 nm ga-abawanye njupụta ndekọ nke MRAM, nke a bụ isi ihe ndọghachi azụ ya.
