Abstract
The column-line short detection circuit of this invention includes a special test circuit that turns off wordlines (15), a N-channel transistor (23) for each column line (18), a decoder (19a) that uses only the least significant column address (20d) for input to the test circuit, and a sensor (SA) to detect current between shorted column lines (18). Because the column-line short detection circuit of this invention uses only the least significant address as input for column decoder (19a), it requires a very small number of transistors.
