Abstract
A level translator includes a programmable booster stage that augments the drive level of the level translator under certain conditions. The booster stage is programmably activated. e.g., via a memory cell or control bit, and augments operation of the pull-up stages of a cross-coupled latch within the level translator. When the voltage levels at the high voltage portion of the level translator are reduced below a threshold voltage, the booster stage is activated to maintain proper operation of the level translator despite the reduced voltage levels.
