ABSTRACT:
A method for forming a semiconductor device comprises forming first and second bit lines at different levels. Forming the bit lines at different levels increases processing latitude, particularly the spacing between the bit lines which, with conventional processes, may strain photolithographic limits. A semiconductor device formed using the method, and an electronic system comprising the semiconductor device, are also described.
