Abstract

A semiconductor device includes local bitlines connected to memory cells, global bitlines disposed at a level higher than a level of the local bitlines and extending in a first horizontal direction, and bitline sense amplifiers connected to the global bitlines. The global bitlines include a first global bitline and a first global complementary bitline, complementary to the first global bitline. The first global bitline includes a 1-1 bitline structure, and the first global complementary bitline includes a 2-1 bitline structure at least partially overlapping the 1-1 bitline structure in the first horizontal direction. The 1-1 bitline structure includes 1-1 lower lines spaced apart from the 1-1 lower lines in the first horizontal direction and a 1-1 upper line disposed on the 1-1 lower lines and connected to the 1-1 lower lines.
