Abstract
A semiconductor memory circuit includes a plurality of programmable memory cells capable of being programmed by a predetermined current; a plurality of bit lines connected with memory cells, a plurality of current distributors corresponding to the bit lines for connecting selected bit lines to an output terminal based on selection signals and separating non-selected bit lines from the output terminal, and a plurality of switching circuits corresponding to the bit lines for connecting non-selected bit lines to a low level potential point based on the selection signals. The determination of the existence of the inter-cell leakage is carried out precisely and easily.
