Abstract
This paper presents an SOI-SRAM design employing a bootstrap scheme for ultra low voltage operation. The active body-biasing control (ABC) with PD-SOI is a key idea to enhance the boosting effect owing to a strong capacitive coupling. Our ABC-bootstrap scheme enables boosting the word line (WL) voltage higher than the supply voltage in short transition time without dual power supply rails. Simulation results have shown improvement in both the access time and operation at ultra low supply voltage less than 0.5V
