摘要：

This paper presents a sense amplifier scheme for low-voltage embedded flash(eFlash) memory applications. The topology of the sense amplifier is based on current mode comparison.Moreover,an offset-voltage elimination technique is employed to improve the sensing performance under a small memory cell current.The proposed sense amplifier is designed based on a GSMC 130 nm eFlash process,and the sense time is 0.43 ns at 1.5 V,corresponding to a 46%improvement over the conventional technologies.
