Spin Transfer Torque (STT) memory is an emerging and promising non-volatile storage technology. However, the high write current is still a major challenge which leads to a huge power consumption of the memory. Due to an inherent torque asymmetry of the Magnetic Tunnel Junction (MTJ) device employed in STT memories, the switching time between parallel to(More)
—Spin Transfer Torque Magnetic Random Access Memory (STT-MRAM) has potential to become a universal memory technology because of its various advantageous features such as high density, non-volatility, scalability, high endurance and CMOS compatibility. However, read disturb is a major reliability issue in which a read operation can lead to a bit-flip,(More)
—Spin Transfer Torque (STT) is a promising emerging memory technology because of its various advantages such as non-volatility, high density, virtually infinite endurance, scalability and CMOS compatibility. Despite all these features, high write current is still a challenge for its widespread use. When writing a value that is already stored, a significant(More)
Magnetic Random Access Memory (MRAM) is a very promising emerging memory technology because of its various advantages such as nonvolatility, high density and scalability. In particular, Spin Orbit Torque (SOT) MRAM is gaining interest as it comes along with all the benefits of its predecessor Spin Transfer Torque (STT) MRAM, but is supposed to eliminate(More)

Radiation-induced multiple event transients (METs) are expected to become more frequent than single event transients (SETs) at nanoscale CMOS technology nodes. In this paper, a fast and accurate layout-based soft error rate (SER) assessment technique with consideration of both SET and MET fault models is presented. Despite existing techniques in which the(More)
With technology scaling, conventional CMOS-based flip-flops can no longer efficiently cope with the increasing leakage power challenge. Therefore, various non-volatile flip-flop designs were recently introduced to reduce the static power consumption. However, these flipflop architectures employ non-volatile Magnetic Tunnel Junction (MTJ) storing devices(More)
This paper deals with a new MRAM technology whose writing scheme relies on the Spin Orbit Torque (SOT). Compared to Spin Transfer Torque (STT) MRAM, it offers a very fast switching, a quasi-infinite endurance and improves the reliability by solving the issue of “read disturb”, thanks to separate reading and writing paths. These properties(More)
