Abstract:
The main theme of my current research is studying embedded memory structures' (especially SRAMs) behavior/stability in deep-sub-micron technologies under aggressive voltage scaling in the presence of process variations (while considering the effect of temperature). Also, I am researching methods of implementing fault tolerant adaptation approaches that are based on the envisioned application (e.g., wireless applications etc). The conventional adaptive techniques for mobile applications assume 100% correctness of data; consequently the design space is two-dimensional, trading off power for performance. Since some systems such as wireless or multimedia are inherently error tolerant, we can add an extra degree of freedom to their design space by extending it in hardware error dimension. This will result in potentially significant savings in power and correspondingly an increase in battery lifetime.
