Abstract
A local X-decoder for a memory system including a decoding unit configured to generate a word line signal to a memory cell of a memory array of the memory system; and a voltage clamping transistor coupled to the decoding unit, and configured to reduce a voltage difference across a global word line signal and the word line signal by an amount of a threshold voltage of the voltage clamping transistor.
