The present invention integrates a WWTM circuit with the write driver circuitry, which is an inherent part of any conventional SRAM design. Thus, a circuit for writing data into and weak write testing a memory cell is provided. In one embodiment, the circuit comprises a write driver that has an output for applying a write or a weak write output signal at the memory cell. The write driver has first and second selectable operating modes. In the first mode, the write driver is set to apply a weak write output signal from the output for performing a weak write test on the cell. In the second mode, the write driver is set to apply a normal write output signal that is sufficiently strong for writing a data value into the cell when it is healthy.
