Patent ID: 7049854

Claim:
A sense amplifier for low voltage sensing that includes a switching circuit, the switching circuit comprising: a pair of low voltage threshold transistors being cross-coupled to a pair of complementary sensing lines so that each transistor of the pair is driven by one of the complementary sensing lines; and a pair of switching transistors, one of the switching transistors being coupled between one of the complementary sensing lines and one of the low voltage threshold transistors and the other of the switching transistors being coupled between the other one of the complementary sensing lines and the other one of the low voltage threshold transistors, the switching transistors being driven by a full internal voltage of a sense amplifier, the switching transistors having gates operably coupled to receiving a switching signal, the switching signal having a time period of approximately between ten and twenty-five nanoseconds, such that the switching signal is pulsed before the sense amplifier starts the low voltage sensing.
