Abstract
A bitline selection apparatus for a semiconductor memory device includes a first local bitline pair and a second local bitline pair selectively coupled to a global bitline pair, each of the first and second local bitline pairs including a true bitline and a complementary bitline. Each of the true bitlines is selectively coupled to a common true node through an n-type pass device and a p-type pass device in parallel therewith, and each of the complementary bitlines is selectively coupled to a common complementary node through an n-type pass device and a p-type pass device in parallel therewith.
