存储器（Memory）是计算机系统中的记忆设备，用来存放程序和数据。计算机中的全部信息，包括输入的原始数据、计算机程序、中间运行结果和较终运行结果都保存在存储器中。它根据控制器*的位置存入和取出信息。

存储器的构成
构成存储器的存储介质，目前主要采用半导体器件和磁性材料。存储器中较小的存储单位就是一个双稳态半导体电路或一个CMOS晶体管或磁性材料的存储元，它可存储一个二进制代码。由若干个存储元组成一个存储单元，然后再由许多存储单元组成一个存储器。 一个存储器包含许多存储单元，每个存储单元可存放一个字节。每个存储单元的位置都有一个编号，即地址，一般用十六进制表示。一个存储器中所有存储单元可存放数据的总和称为它的存储容量。假设一个存储器的地址码由20位二进制数（即5位十六进制数）组成，则可表示220，即1M个存储单元地址。每个存储单元存放一个字节，则该存储器的存储容量为1KB。

INTRODUCTION
The MR2A16A is a 4,194,304-bit magnetoresistive random access memory (MRAM) device organized as 262,144 words of 16 bits. The MR2A16A offers SRAM compatible 35 ns read/write timing with unlimited endurance. Data is always non-volatile for greater than 20 years. Data is automatically protected on power loss by low-voltage inhibit circuitry to prevent writes with voltage out of specification.

The MR2A16A is the ideal memory solution for applications that must permanently store and retrieve critical data and programs quickly.

The M2A16A is available in a small footprint 48-pin ball grid array (BGA) package and a 44-pin thin small outline package (TSOP Type 2). These packages are compatible with similar low-power SRAM products and other nonvolatile RAM products.

The MR2A16A provides highly reliable data storage over a wide range of temperatures. The product is offered with Commercial (0 to +70 °C), Industrial (-40 to +85 °C), Extended (-40 to +105 °C), and AEC-Q100 Grade 1 (-40 to +125 °C) operating temperature range options.
