The present disclosure relates to a method and apparatus for performing a read operation of an RRAM cell, which applies a non-zero bias voltage to unselected bit-lines and select-lines to increase a read current window without damaging corresponding access transistors. In some embodiments, the method may be performed by activating a word-line coupled to a row of RRAM cells comprising a selected RRAM device by applying a first read voltage to the word-line. A second read voltage is applied to a bit-line coupled to a first electrode of the selected RRAM device. One or more non-zero bias voltages are applied to bit-lines and select-lines coupled to RRAM cells, within the row of RRAM cells, having unselected RRAM devices.
