Provided is a phase change random access (PRAM) memory. The PRAM may include a memory cell array having a plurality of phase change memory cells, and a data read circuit including a compensation unit and a sense amplifier, the compensation unit configured to provide a sensing node with a compensation current to compensate for a decrease in a level of the sensing node caused by a current flowing through one of the plurality of phase change memory cells, and the sense amplifier configured to compare a level of the sensing node with a reference level and output a result of the comparison.
