Cache design resilient to contention-based side-channel attack
Background Shared caches are vulnerable to side channel attacks through contention in cache sets. Contention attacks, as opposed to reuse attacks, depend on having a shared cache between the attacker and the victim and do not require the presence of shared memory. Existing solutions to prevent these attacks resort to partitioning or hiding the mapping...

Multispectral Imaging CMOS Sensor
ProblemMultipixel image sensors are widely used in digital camera, LIDAR, medical imaging devices, and other equipment. For color image sensors, typically arrays of pixel elements are used for each pixel position. Light reaches each pixel element through a respective color filter, so each pixel element responds primarily to a single color, for example...

High-sensitivity low-energy thermal aware system for next generation integrated systems
Background In next-generation integrated systems, high power densities and thermal issues can dramatically degrade performance, reliability, leakage current, and system robustness. Allocating heat conduction paths and specialized cooling systems can help protect from overheating, but these systems must be supported with a temperature aware capability...

Magnetization Switching of a Ferromagnetic Layer Using Spin-Orbit Torques in the Absence of any External Magnetic Field
Background SOT-MRAM is based on the reversible switching of the magnetization of one of two ferromagnetic layers in the magnetic tunnel junction (MTJ) due to the magnetic field created by an in-place current pulse. This causes the magnetization of the switchable ferromagnetic layer to precess toward an in-plane direction. After the current passes,...
