Abstract

At least one method, apparatus and system disclosed involves testing a dual port memory cell in a memory device. A semiconductor wafer is processed for providing a dual port memory device. An inline DC contention margin test is performed for testing a contention margin related to a write operation into a cell of the memory device. A determination is made as to whether the contention margin is within a predetermined range. A responsive action is performed in response to determining that the contention margin is outside the predetermined range.
