The DRAM word line requires higher voltages to activate the access transistor, ensuring fast access during the on state and ultra-low leakage during the off-state. The availability of the 2.5V VPP means that the word line voltage does not have to be inefficiently supplied (pumped up) from the 1.2V VDDQ supply, thereby improving energy/power efficiency.1 }* Z! q, ?7 ^0 U. l
