磁性隨機存儲器芯片(MRAM)磁性隨機存儲器芯片(MRAM)

一種非揮發性的磁性隨機存儲器。
它擁有靜態隨機存儲器(SRAM)的高速讀取寫入能力,
以及動態隨機存儲器(DRAM)的高集成度,而且基本上可以無限次地重復寫入
Everspin MRAM其原理是利用電子自旋的磁性結構,來提供不會產生損耗的非揮發特性。
Everspin MRAM可在集成了硅電路的磁性材料中存儲信息,以在單一、可無限使用的組件中提供SRAM的速度以及閃存的非揮發特性。

Application Note: DDR3 ST-MRAM in Enterprise SSD
Utilizing Everspin ST-MRAM in an Enterprise SSD to greatly reduce power-fail energy storage while increasing SSD performance and density
 
Application Note:  As Enterprise SSDs continue to push the envelope in terms of system performance and smaller form factors, SSD solutions providers are facing greater challenges to increase performance and density while continuing to protect data-in-flight from power failures. NAND flash has not significantly increased in performance and the improvement in SSD performance is typically made by adding more parallel channels of flash. This increases the need for energy storage for power fail protection which in turn reduces space available for the storage array for a fixed form factor.
 
This app note explores the SSD architecture benefits of employing Everspin ST-MRAM on the DDR bus of the SSD controller to provide a high speed, nonvolatile write buffer in order to reduce power fail energy storage while increasing performance and storage density.
