A programmable level shifter. The programmable level shifter comprises a first P-type FET, a first N-type FET, a second P-type FET, a second N-type FET, and a programmable device. The first P-type FET is coupled between a fist power line and a non-inverted output node, and a gate pole thereof is coupled to a inverted output node. The first N-type FET is coupled between the first P-type FET and a second power line. The programmable device is coupled between the first power line and the non-inverted output node, which can be programmed to change an effective resistance between the first power line and the inverted output node when the second P-type FET is turned on.
