Abstract

A test system includes row decoder, column decoder, row test controller, and test circuit. The row decoder activates one of first through M-th row signals based on plurality of row input signals. The column decoder activates one of first through N-th column signals based on plurality of column input signals. The row test controller outputs first through N-th column output signals, which are activated, when row test enable signal is activated. The row test controller outputs the first through N-th column signals as the first through N-th column output signals respectively when the row test enable signal is deactivated. The test circuit includes first through M-th row test blocks, each of which includes first through N-th test units. The test circuit simultaneously performs short test of the first through N-th test units included in row test block when the row test enable signal is activated.
