A reading circuit in a memory, having a first memory cell coupled to a first bit line and a second bit line, a second memory cell coupled to the second bit line and a third bit line and a third memory cell coupled to the third bit line and a fourth bit line, is provided. The reading circuitry includes a sensing circuit, a drain side bias circuit, a first selection circuit and a second selection circuit. The drain side bias circuit provides a drain side bias. The first selection circuit connects the second bit line to the drain side bias circuit to receive the drain side bias in a read operation mode. The second selection circuit connects the first bit line and the fourth bit line to the sensing circuit in the read operation mode, so that the sensing circuit senses a current of the first memory cell.
