　　INTRODUCTION

　　The MR256A08B is a 262,144-bitmagnetoresistive random access memory (MRAM) device organized as 32,768 wordsof 8 bits. The MR256A08B offers SRAM compatible 35ns read/write timing with un-limitedendurance.

　　Data is always non-volatile for greaterthan 20-years. Data is automatically protected on power loss by low-voltageinhibit circuitry to prevent writes with voltage out of specification.

　　The MR256A08B is the ideal memory solutionfor applications that must permanently store and retrieve critical data andprograms quickly.

　　The MR256A08B is available in a smallfootprint 400-mil, 44-lead plastic small-outline TSOP type-2 package, or an 8mm x 8 mm, 48-pin ball grid array (BGA) package. (The 32-SOIC package optionsis obsolete and no longer available for new orders.) All package footprints arecompatible with similar low-power SRAM products and other non-volatile RAMproducts.

　　The MR256A08B provides highly reliable datastorage over a wide range of temperatures. The product is offered withcommercial temperature (0 to +70 °C) and industrial temperature (-40 to +85 °C)range options.
