Abstract
A method for detecting voltage supply short circuits in integrated circuits and a circuit for implementing that method is disclosed. Entire rows of memory cells in an SRAM are coupled to a single sense line. The sense line to each row is activated individually. The sense lines are in turn coupled to a current sensing circuit. If a short exists on any memory cell in a given row, the current sensing circuit generates a low output, indicating a short circuit.
