1. A method for reading a memory, comprising:
providing, by a decoding circuit, a first signal according to first data of the memory and a second signal according to second data of the memory in response to a first address signal, wherein binary representation of the first signal is complementary to that of the second signal;
providing, by a sensing circuit, a first sensing signal according to a reference signal and the first signal, and a second sensing signal according to the reference signal and the second signal; and
outputting, by an output buffer, an output corresponding to the first sensing signal or the second sensing signal in response to a control signal.
