Low-leakage architecture for embedded ROM

Low-leakage architecture for embedded ROM Register File (RF), Static Random Access Memory (SRAM) and Read Only Memory (ROM) arrays on SoCs comprise over 50% area and consumes substantial power on die. The On die ROM usage is increasing as there is an increased focus on IOTs, multi-core microprocessor for notebooks, 2-in-1s and mobile applications. Achieving high performance at low power specification need considerable innovation. Use of High Threshold Voltage (Vth) devices may not be the solution when targeting high performance designs. Further, as technology scales, leakage increases exponentially, which requires more aggressive low leakage power schemes.
