MRAM is a non-volatile magnetic random access memory. It has the high-speed reading and writing capabilities of SRAM, and the high integration of DRAM, and can basically repeat writing infinitely. MRAM is an ideal memory chip for automotive applications. MRAM is fast and non-volatile. Sensor data monitored in real time can be written in real time without load balancing or ECC overhead. AEC-Q100 Grade 1 qualified MRAM will retain data for 20 years at the extended temperatures (-40°C to 125°C) found in under-hood applications. Unplanned power outages will not affect data integrity.
For example, Everspin MR2A16A 4Mbit MRAM memory chip, MR2A16A provides 35ns read/write timing compatible with SRAM, and has unlimited battery life. Data is always non-volatile for more than 20 years. Data is automatically protected during power failure by a low voltage suppression circuit to prevent writing when the voltage exceeds the specification.
Everspin's MRAM technology is very robust and reliable in extreme temperature ranges, which is very suitable for the requirements of memory products in the automotive market. Everspin is dedicated to the automotive market and offers a range of AEC-Q100 qualified products. All aspects of the market requirements are covered.
