摘要
The recent advent of spin transfer torque (STT) has shed a new light on MRAM with the promises of much improved performances and greater scalability to very advanced technology nodes. As a result, MRAM is now viewed as a credible solution for stand-alone and embedded applications where the combination of non-volatility, speed and endurance is key. Whereas the technology is nearing maturity for DRAM replacement, with the exception of process scaling to sub-20nm which remains a challenge, circuit designers are now actively looking at SoCs where MRAM could bring in better performance and lower power consumption in data intensive applications as well as instant-on capability in mobile applications. In this paper we present a review of the MRAM technology and a methodology for ASIC design using a custom full digital hybrid CMOS/Magnetic Process Design Kit. We finish by a few examples showing that magnetic memories can be efficiently integrated in logic designs, for both safety and low power purposes.
