摘要:
A layout structure of bit line sense amplifiers for use in a semiconductor memory device includes first and second bit line sense amplifiers arranged to share and be electrically controlled by a first column selection line signal, and each including a plurality of transistors. In this layout structure, each of the plurality of transistors forming the first bit line sense amplifier is arranged so as not to share an active region with any transistors forming the second bit line sense amplifier.

摘要:
A memory core having an open bit line structure and a semiconductor memory device having the memory core includes an edge sub-array and a dummy bit line control circuit. The edge sub-array has a plurality of word lines, a plurality of bit lines and a plurality of dummy bit lines. The dummy bit line control circuit amplifies and latches voltage signals of the dummy bit lines in a test sensing mode. Accordingly, the semiconductor memory device having the memory core may test defects of the edge sub-array included in the memory core.
