Abstract:
Memory devices include a row decoder, a first variable resistance memory cell connected to a first bit line and connected to the row decoder by a word line and a second variable resistance memory cell connected to a second bit line and connected to the row decoder by the word line. The memory devices further include a bit line select circuit coupled to the first and second bit lines and configured to compensate for a difference in word line resistance between the row decoder and the respective first and second memory cells. In some embodiments, the bit line select circuit includes first and second transistors configured to selective respective ones of the first and second bit lines and the first and second transistors have different resistances that compensate for the difference in word line resistance.
