Abstract

In this paper a current mode sense amplifier suitable for 30nm SONOS flash memories read operation is presented. The proposed sense amplifier employs cross coupled latch type circuit and current mirror to amplify signal from selected memory cell. This sense amplifier provides fast response in low voltage and low current dissipation. Simulation results show the sensing delay time and current dissipation for power supply voltages Vdd to expose limitations of the sense amplifier in various operating conditions.
