Layout structures of data input/output pads and peripheral circuits of integrated circuit memory devices

摘要

Integrated circuit memory devices include a first memory block. The first memory block includes first and second memory array banks and a first peripheral circuit. The first peripheral circuit is disposed between the first and second memory array banks such that a length of a first data path from the first memory array bank to the first peripheral circuit is about equal to a length of a second data path from the second memory array bank to the first peripheral circuit.
