A phase-change memory device is provided. The phase-change memory device
includes a phase-change memory cell array including a first memory block
having a plurality of phase-change memory cells each connected between
each of a plurality of bit lines and a first word line, a second memory
block having a plurality of phase-change memory cells each connected
between each of the plurality of bit lines and a second word line, and
first and second pull-down transistors pulling-down each voltage level of
the first and the second word lines and sharing a node and a row driver
including a first and a second pull-up transistor pulling-up each voltage
level of the first and the second word lines.
