A 1.35-V sense amplifier for non volatile memories based on current mode approach

Abstract

A sense amplifier for nonvolatile memories, based on a novel topology which has the benefit of a pure current mode comparison, is presented. The sense amplifier is capable of working under a very low voltage power supply - as low as 1 V, and was implemented in an EEPROM realized with a 0.18 /spl mu/m EEPROM technology. Setting the power supply at 1.65 V, experimental results shown a read access time of about 30 ns.
