The MR256D08BMA45 is a dual supply magnetoresistive random access memory (MRAM) device organized as 32,768 words of 8 bits.

This device offers SRAM compatible 45ns read/write timing with unlimited endurance. The data is always non-volatile for greater than 20-years and is automatically protected on power loss by low-voltage inhibit circuitry to prevent writes with voltage out of specification. It is available in small footprint 8 mm x 8 mm, 48-pin ball grid array (BGA) package with 0.75 mm ball centers.


  • +3.3 Volt power supply
  • I/O Voltage range supports wide +1.65 to +3.6 Volt interfaces
  • Fast 45 ns read/write cycle
  • SRAM compatible timing
  • Unlimited read & write endurance
  • Data always non-volatile for >20-years at temperature
  • RoHS-compliant small footprint BGA package


  • One memory replaces FLASH, SRAM, EEPROM and BBSRAM in system for simpler, more efficient design
  • Improves reliability by replacing battery-backed SRAM
