Abstract
A memory device includes a first memory cell array connected to a first internal data line; a second memory cell array connected to a second internal data line; and a line swap circuit configured to connect the first and second internal data lines with first and second external data lines based on an externally received driving signal. The line swap circuit is configured such that, when the driving signal has a first logic level, the line swap circuit connects the first and second internal data lines with the first and second external data lines, respectively, and when the driving signal has a second, different logic level, the line swap circuit swaps the first and second external data lines so that the first internal data line is connected to the second external data line and the second internal data line is connected to the first external data line.
