INTRODUCTION
By the early 1960’s, Magnetic Core RAM became largely universal as main memory, replacing drum memory
MRAM uses magnetism rather than electrical power to store bits of data.
Ferro-magnet
Ferro-magnet is the type
of material used to develop
MRAM
Why MRAM
Why MRAM Became an Important Research Topic
Universal Memory (Computing & Electronics)
“Instant-On” Computing
Read & Write to Memory Faster
Reduced Power Consumption
Save Data in Case of a Power Failure
Modern MRAM Technology Emerged from Several Technologies :
Magnetic Core Memory
Magnetoresistive RAM
Giant Magnetoresistance
Basic Principle
The 2 Possible Magnetization States of a Ferromagnetic Element can be Described by a Hysteresis Loop
Magnetization of Film vs. Magnetic Field
