Abstract:
A sense amplifier comprising:a pair of pass transistors having first and second inputs respectively connected to a data path and complementary data path for receiving a differential data signal, the pair of pass transistors respectively connecting the data path and complementary data path at first and second outputs thereof in response to a sense enable signal, the first and second inputs of the pair of pass transistors are not electrically the same as the first and second outputs thereof when the pair of pass transistors are disabled by the sense enable signal; and an amplifier having a first input connected to the first output of the pair of pass transistors, a second input connected to the second output of the pair of pass transistors, and first and second outputs for providing sense amplifier data signals in complementary form, the amplifier being controlled by the sense enable signal and being operative only when the pair of pass transistors are made nonconductive by the sense enable signal.
