Abstract
Systems and methods to provide sense amplifiers for various applications. For example, in accordance with an embodiment of the present invention, a sense amplifier is disclosed having an associated precharge circuit and a read completion detection circuit.
Claims14
A sense amplifier circuit comprising:
- a sense amplifier coupled to a first input line and a second input line and adapted to receive an enable signal, wherein the enable signal controls whether the sense amplifier is enabled;
- a first inverter coupled to the first input line and adapted to provide a first output signal;
- a second inverter coupled to the second input line and adapted to provide a second output signal;
- and
- a logic gate adapted to receive the first output signal and the second output signal and to provide a trip signal.
2 more elements
A method of reading data from data lines, the method comprising:
- disabling a sense amplifier coupled to the data lines;
- precharging the data lines;
- providing a first signal value via inverters coupled to the data lines when the data lines are precharged;
- providing the data on the data lines after the first signal value is provided;
- enabling the sense amplifier to read the data placed on the data lines after the first signal value is provided;
- and
- providing a second signal value via the inverters coupled to the data lines when the sense amplifier has read the data placed on the data lines.
