MRAM
Stands for Magneto resistive Random Access
Memory
MRAM uses magnetic fields rather electrical
charges to store and randomly access data
NON VOLATILE: information save when there is
power

Construction of
MRAM
• MRAM bit cell
consist of two
ferromagnetic
layers.
• Layers are
separated by an
insulating tunnel
barrier in a
sandwich like
structure.
