摘要:
A phase change memory device includes a memory cell having a phase change material, a write driver adapted to supply a program current to the memory cell during a programming interval, and a pump circuit adapted to enhance a current supply capacity of the write driver during the programming interval. The pump circuit is activated prior to the programming interval in response to an external control signal.
