Abstract
A three-dimensional block includes a stack comprising a plurality of control gate layers configured to bias memory cells of the block. The block includes a plurality of track regions that includes three or more hookup regions. The plurality of track regions separate the memory cells into three memory cell regions. Tracks extending in the track regions supply voltages to the hookup regions. A system includes a memory plane of blocks, and a plurality of track regions, each extending across the memory plane of blocks.
