The minimum voltage of operation (Vmin) for memory arrays often limits the lowest system operating voltage. This paper introduces a novel read assist topology for a domino-based evaluation architecture in a read only memory (ROM). The implementation incorporates an assist pull-down (PD) device, which activates during the evaluation phase in order to increase the effective pull-down strength of the bit cells. This implementation maintains Vmin without increasing the size of pull down devices inside the bit cells. The assist topology improves read delay by 11-30% and increases noise margin. Area overhead can be limited to 27% in a typical ROM.
