INTRODUCTION
The MR4A08B is a 16,777,216-bit magnetoresistive random access memory (MRAM) device organized as 2,097,152 words of 8 bits. The MR4A08B offers SRAM compatible 35ns read/write timing with unlimited endurance. Data is always non-volatile for greater than 20-years. Data is automatically protected on power loss by lowvoltage inhibit circuitry to prevent writes with voltage out of specification. The MR4A08B is the ideal memory solution for applications that must permanently store and retrieve critical data and programs quickly.
FEATURES
