ABSTRACT:
A SONOS memory sensing scheme includes a reference current circuit that tracks the changes in the power supply (Vcc). An equalizer of the current sense amplifier is coupled between the read out current line and the reference current line. The current sense amplifier includes data and datab (data bar) outputs which have a common mode noise due to variations in the power supply voltage. The data output is a current generated from the memory cell, and the datab output is generated by the current reference circuit.
