磁性随机存储器芯片(MRAM)磁性随机存储器芯片(MRAM)

一种非挥发性的磁性随机存储器。
它拥有静态随机存储器(SRAM)的高速读取写入能力,
以及动态随机存储器(DRAM)的高集成度,而且基本上可以无限次地重复写入
Everspin MRAM其原理是利用电子自旋的磁性结构,来提供不会产生损耗的非挥发特性。
Everspin MRAM可在集成了硅电路的磁性材料中存储信息,以在单一、可无限使用的组件中提供SRAM的速度以及闪存的非挥发特性。

Everspin 64Mb DDR3 Spin-Torque MRAM

The EMD3D064M08B1 is an 8Mb x 8 Spin-Torque MRAM capable of DDR3 operation at rates of up to 800MT/sec/pin.  
It is available in a 9 x 13mm BGA package.
 
Everspin 256Mb DDR3 Spin-Torque MRAM
 The EMD3D256M08G1 32Mb x 8 or EMD3D256M16G2 16Mb x 16 Spin-Torque MRAM capable of DDR3  operation at rates of up to 1333MT/sec/pin. 
It is available in a 78-ball [x8] or a 96-ball [x16] 10 x 13mm BGA package.



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.
