Τίτλος: Energy efficient and high speed digital integrated circuits and embedded memories Περίληψη: Advances in technology and the growth of mobile applications have made energy consumption, which poses one of the fundamental limits in both high performance microprocessors and low to medium performance portable systems, a prime focus of attention in Integrated Circuits (IC) digital design. In combinational and memory circuits there is a clear tradeoff between energy and delay, so the cost of optimizing one results in the degradation of its counterpart. This is why achieving high performance at low energy consumption is such a challenge.
Many design techniques have been successfully applied to reduce both the dynamic and the leakage components of embedded memories and logic. When discussing low/medium frequency applications, memory and logic operation in the sub/near-threshold regions has been shown to be the ideal choice. Circuits operating in the sub/near-threshold regions utilize a low supply voltage that is close to or even less than the threshold voltages of the transistors.
In this lecture, I will introduce the audience to low voltage SRAM memories and review the advantages of SRAMs operating in the sub/near-threshold regions, compared to their conventional strong inversion counterparts. Then, I will discuss design and reliability challenges in advanced nanoscale CMOS technologies. New design approaches and memory architectures, such as SF-SRAM, Q-SRAM, 4T eDRAM for aggressive power reduction and ultra-low voltage operation, will be shown.
Then, we will overview a variety of alternative (non standard) circuit level solutions developed to achieve energy efficient and high performance digital integrated circuits. In particular, the Dual Mode Logic (DML) family and its accompanying design methodology will be described. DML presents a unique concept that enables an on-the-fly tradeoff between high performance (Dynamic mode) and energy efficient (Static mode) operation. This flexibility provides the option of meeting the required performance with significant reduction of energy and area.
