　　INTRODUCTION

　　The MR4A16B is a 16,777,216-bitmagnetoresistive random access memory (MRAM) device organized as 1,048,576words of 16 bits. The MR4A16B offers SRAM compatible 35 ns read/write timingwith unlimited endurance. Data is always non-volatile for greater than 20years. Data is automatically pro-tected on power loss by low-voltage inhibitcircuitry to prevent writes with voltage out of specification. To simplifyfault tolerant design, the MR4A16B includes internal single bit errorcorrection code with 7 ECC parity bits for every 64 data bits. The MR4A16B isthe ideal memory solution for applications that must permanently store andretrieve critical data and programs quickly.

　　The MR4A16B is available in a smallfootprint 48-pin ball grid array (BGA) package and a 54-pin thin small outlinepackage (TSOP Type 2). These packages are compatible with similar low-powerSRAM products and other nonvolatile RAM products.

　　TheMR4A16B provides highly reliable data storage over a wide range oftemperatures. The product is offered with commercial temperature (0 to +70 °C),and industrial temperature (-40 to +85 °C) operating temperature options.
