Semiconductor memory device having mount test circuits and mount test method thereof










Image Number 4 for United States Patent #8108741.

A semiconductor memory device having a mount test circuit and a mount test method thereof are provided. The test circuit for use in a semiconductor memory device including a plurality of memory blocks may include a comparison unit for comparing test data of at least two memory blocks selected from the plurality of memory blocks, deciding whether or not the test data of the selected memory blocks are identical, and outputting a pass signal or fail signal as a flag signal; and an output selection unit for selecting any one of the selected memory blocks as an output memory block, and changing the output memory block whenever the fail signal is generated from the comparison unit, thus forming it as a data output path, which may lessen error occurrence.
