Claim Text:
1. A voltage level shifter comprising a boosted node having a voltage; an input port to receive an input logic signal in a first voltage domain; an output port to provide an output logic signal in a second voltage domain in response to the input logic signal; a voltage boost module coupled to the boosted node to boost the voltage of the boosted node when the input logic signal transitions from a LOW voltage to a first HIGH voltage in the first voltage domain; a node discharge module coupled to the boosted node to discharge the boosted node for a time interval when the input logic signal transitions from the first HIGH voltage to the LOW voltage; and a pull-up module coupled to the boosted node, the boosted node to turn OFF the pull-up module when boosted by the voltage boost module, wherein the pull-up module operates in the second voltage domain.
