The read current is about a third of write current. The switching time depends on current, the lower current requires longer time. A long enough read could do it. But scaled down resistance goes up, slowing down read anyway.
What is the speed and current consumption for writing SST-MRAM? Write disturbance is a very serious issue for old MRAM. What is the write disturbance for present vertical SST-MRAM? Apreciate your comments.
