Abstract
A semiconductor memory device having resistive bitline contact testing includes memory cells, and wordline logic devices for concurrently activating two adjacent memory cells. The two adjacent memory cells are activated concurrently to allow higher current through a bitline contact for improved detection of resistive bitline contacts. A test cell may also be included to test the integrity of the bitline contact.
