Abstract
High leakage current in deep-submicrometer regimes is becoming a significant contributor to power dissipation of CMOS circuits as threshold voltage, channel length, and gate oxide thickness are reduced. Consequently, the identification and modeling of different leakage components is very important for estimation and reduction of leakage power, especially for low-power applications. This paper reviews various transistor intrinsic leakage mechanisms, including weak inversion, drain-induced barrier lowering, gate-induced drain leakage, and gate oxide tunneling. Channel engineering techniques including retrograde well and halo doping are explained as means to manage short-channel effects for continuous scaling of CMOS devices. Finally, the paper explores different circuit techniques to reduce the leakage power consumption.

Energy-efficient Spin-Transfer Torque RAM cache exploiting additional all-zero-data flags

TL;DR: This paper provides an architectural technique which exploits the fact that many applications process a large number of zero data and appends additional flags in cache tag arrays and set these additional bits if the corresponding data in the cache line is the zero-valued data in which all data bits are zero.
