MRAM Data Losing Problem

ctarakci over 5 years ago

Hi All,

I want to use MR2A16A MRAM for my application. I initialize FMC for 18 Bit address and 16 Bit data . I assumed that I can write and read data successfuly. I saw when I debug but when I restart mcu or cut down power MRAM lost its data. How can it be possible when you write data successfuly to MRAM ?

Thanks in advanced
