Abstract :
In this paper two-stage sense amplifier designs are proposed which are suitable for current sensing in SRAM and flash memories read operations. The first-stage of these sense amplifiers is characterized by its low power operation and its small area overhead which requires only three transistors in the pitch of a bit line pair for the sensing of the stored data in the selected memory cell. Compact layout designs and simulations in 0.25 μm CMOS technology have been carried out to evaluate the efficiency of the proposed schemes
