Abstract
Technology for driving word lines in 3D memory. Even numbered word lines in a 3D memory are biased from one end of the word lines and odd numbered word lines in the 3D memory are biased from the other end of the word lines. The word lines may reside in a stack of alternating conductive and dielectric layers, with the conductive layers serving as the word lines as well as select lines. The ends of the word lines on one side of the stack may form a first staircase and the ends of the word lines on an opposite side of the stack may form a second staircase. A first set of word line driver transistors connect to the even numbered word lines at the first staircase and a second set of word line driver transistors connect to the odd numbered word lines at the second staircase.
