次世代記憶體大戰開打,英特爾研發「3D cross point」技術,擬推「PRAM」。三星電子
不甘示弱,發表「MRAM」(magnetoresistant random access memory,磁阻式隨機存取
記憶體),號稱讀寫速度比 NAND Flash 快上一千倍。
fudzilla、IBTimes、南韓經濟日報報導,三星 24 日發表「MRAM」,此種次世代記憶體
兼具 NAND Flash 和 DRAM 的優點,無須電源也能儲存資料,而且處理速度極快。三星宣
稱,MRAM 是非揮發性記憶體,採用自旋傳輸科技(Spin-torque transfer)讀寫數據,
速度比 NAND 快了一千倍。不僅如此,MRAM 更省電,使用時(active)耗電量比傳統記
憶體少,停用時(inactive)更無需用電。
目前次世代記憶體包括 MRAM、PRAM、ReRAM,其中 MRAM 速度最快,但是量產難度較高。
現在三星只能少量生產,但是預期能盡速克服生產障礙。
三星同時宣布,歐洲大廠恩智浦半導體(NXP Semiconductors)的物聯網半導體將採用
MRAM,雙方簽訂晶圓代工協定,將量產 28 奈米的全耗盡型絕緣層上矽(FD-SOI)。
IBTimes 猜測,倘若三星 MRAM 量產進展順利,或許今年下半問世的 Galaxy Note 8 就
會內建 MRAM,以便做出市場區隔。MRAM 用於智慧手機可加快處理速度,並更為省電。

Intel有3D cross point (PRAM)
三星有MRAM
台灣咧? 記憶體廠都差不多玩完了...GG又沒做記憶體
