    Abstract: A resistive memory device includes memory cell array blocks, a reference cell array block, two first and second sink transistors, and a word line. Each of the memory cell array blocks includes a row line, and the reference cell array block includes a reference row line. One of the first sink transistors is disposed between one end of the row line and a ground and the other of the first sink transistors is disposed between an opposite end of the row line and the ground. One of the second sink transistors is disposed between one end of the reference row line and the ground and the other of the second sink transistors is disposed between an opposite end of the reference row line and the ground. The word line is coupled to gates of the first and second sink transistors.

    Abstract: A magnetic memory device includes a substrate, a landing pad on the substrate, first and second magnetic tunnel junction patterns disposed on the interlayer insulating layer and spaced apart from the landing pad when viewed from a plan view, and an interconnection structure electrically connecting a top surface of the second magnetic tunnel junction pattern to the landing pad. A distance between the landing pad and the first magnetic tunnel junction pattern is greater than a distance between the first and second magnetic tunnel junction patterns, and a distance between the landing pad and the second magnetic tunnel junction pattern is greater than the distance between the first and second magnetic tunnel junction patterns, when viewed from a plan view.
