摘要：
A sense amplifier for a memory device comprising: a first sensing stage comprising a first sensing device and a second sensing device operably connected to a first sense line and a second sense line respectively, to reduce the capacitive load on the first sense line and second sense line. A source terminal of the sensing device is connected to a switchable current sink with drain terminal thereof connected to an input of a second sensing stage. The sense amplifier also includes a second sensing stage comprising cross-coupled inverters responsive to the first sensing stage, the second sensing stage is activated by a sense enable signal following a selected delay, and an output driver responsive to the second sensing stage.
