Application
Automobiles
Modern cars are equipped with numerous sensors to record critical data from fuel injection, ignition, braking, acceleration, etc. As cars become "smarter", additional processing of this data is required, and at the same time, the amount of memory used in MCUs is increasing. This memory needs to remain non-volatile at temperatures above 100 degrees Celsius. For these manufacturers, memory performance, durability, and reliability are the most important issues. The unique advantages of MRAM will gradually emerge.

*Estimated chip performance, simulation results
BMW superbikes and Lucid AIR both use parallel interface MRAM. It provides 35ns access time, an operating temperature range of -40 to 125 degrees, consumes 300mW during writing and 200mW during reading. The 4Mb VC-MeRAM chip provides more than 2 times the speed in the same operating temperature range while reducing power consumption by 3 times, which shows the superior performance of the third generation MRAM.
