Integrating Semantic Memory into a Cognitive Architecture

Semantic memory stores a person's general knowledge about the world and plays an important functional role in generating intelligent behaviors. Semantic memory has been an active research field in psychology and is implemented in cognitive architectures such as ACT-R [1] to model various related phenomena in human. However, functionally-based cognitive architectures, such as Soar [2], have not ...

Composite magnetic tunnel junctions for fast memory devices and efficient spin-torque nano-oscillators

We investigate a possibility to use composite magnetic tunnel junction structures (MTJs) to compose fast memory devices and efficient spin-torque nano-oscillators. In terms of magnetic memory, we study the switching statistics dependence on memory cell geometry by means of systematic micromagnetic simulations. We find that MTJs with a free layer composed of two ellipses with the axes a/2 > b in...
