Abstract
A memory device includes a three dimensional memory array having memory cells arranged on multiple floors in rows and columns. Each column is associated with a bit line and a select line. The memory device further includes select gate pairs each being associated with a column. The bit line of a column is connectable to a corresponding a global bit line through a first select gate of a select gate pair associated with the column and a select line of the column is connectable to a corresponding global select line through the second select gate of the select gate pair associated with the column. The plurality of select gate pairs are formed in a different layer than the plurality of memory cells.
