A monolithic three-dimensional memory array is provided that includes global bit lines disposed above a substrate, each global bit line having a long axis, vertically-oriented bit lines disposed above the global bit lines, word lines disposed above the global bit lines, memory cells coupled between the vertically-oriented bit lines and the word lines, and vertically-oriented bit line select transistors coupled between the vertically-oriented bit lines and the global bit lines. Each vertically-oriented bit line select transistor has a width, a first control terminal and a second control terminal. The word lines and the vertically-oriented bit lines have a half-pitch, and the width of the vertically-oriented bit line select transistors is between about two times the half-pitch and about three times the half-pitch. Vertical bit lines disposed above adjacent global bit lines are offset from one another in a direction along the long axis of the global bit lines.
