The MR256A08BYS35 is a magnetoresistive random access memory (MRAM) device organized as 32,768 words of 8 bits. It is available in small footprint 400-mil, 44-lead plastic small-outline TSOP type-2 package.

This device offers SRAM compatible 35 ns read/write timing with unlimited endurance. The data is always non-volatile for greater than 20-years and data is automatically protected on power loss by low-voltage inhibit circuitry to prevent writes with voltage out of specification.


  • 3.3 Volt power supply
  • Fast 35 ns read/write cycle
  • SRAM compatible timing
  • Native non-volatility
  • Unlimited read & write endurance
  • Data always non-volatile for >20-years at temperature
  • Commercial and industrial temperatures
  • RoHS-Compliant SOIC packages


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