A method of accessing a resistive memory device can include applying a predetermined voltage level to a first word line coupled to a first resistive memory cell block during a read operation of a second resistive memory cell block coupled to a second word line, A programming current can be conducted via a pair of opposing current source transistors located on first and second opposing sides of the first block to provide the programming current from the first end to the second end across bit lines coupled to resistive memory cells in the first block and to provide the programming current parallel to the second block.
