ABSTRACT:
Conductive straps are connected to a subset of word lines of a memory device. Alternatively, first conductive straps are respectively connected only to first portions of first word lines of a memory device, and second conductive straps are respectively connected only to second portions of second word lines of the memory device, where each first word line is adjacent at least one second word line. One or more contacts can be used to connect a conductive strap to its respective word line.
