A novel offset-cancelling current-mode sense amplifier (OC-CSA) to improve the sensing speed of embedded flash (eFlash) memory is proposed. To reduce the precharge time related to random address transitions, this OC-CSA adopts a new precharge acceleration scheme. Moreover, by employing offset cancellation, double sensing margin and strong positive feedback techniques, the new OC-CSA can achieve a sensing speed 1.6 × faster than other OC-CSAs. A 130 nm 1 Mb eFlash macro to confirm the high-speed capability of the proposed OC-CSA is fabricated. The experiment results show the new OC-CSA can achieve a read access time of 11 ns at VDD = 1.3 V.
