    摘要: A phase change memory device may include a memory cell array, a write driver, and/or a control unit. The memory cell array may include a plurality of memory cells. The write driver may be configured to provide a program current to the memory cell array for setting a state of a phase change material to program a selected memory cell. The write driver may be configured to provide the program current such that the program current has a plurality of steps. The control unit may be configured to receive step information for adjusting a magnitude and a width of each step of the program current during a test operation and provide the step information to the write driver during a normal operation.
