Abstract: A method testing an SRAM having a plurality of memory cells is disclosed. In a first step, a bit value is written into a cell under test (CUT). Subsequently, the first and second enabling transistors are disabled and the bit lines are discharged to a low potential. Next, the word line (WL) coupled to the memory cell under test is activated for a predetermined period. During a first part of this period, one of the bit lines (BLB) is kept at the low potential to force the associated pull up transistor in the CUT into a conductive state, after which this bit line (BLB) is charged to a high potential. Upon completion of this period, the bit value of the first cell is determined. The method facilitates the detection of weak or faulty SRAM cells without requiring the inclusion of dedicated hardware for this purpose.
