Abstract

A memory device including a memory cell, a first circuit, and a second circuit. The memory cell includes phase-change material. The first circuit is configured to provide pulses to the phase-change material and to program each of more than two states into the memory cell. The second circuit is configured to sense the present state of the memory cell and provide signals that indicate the present state of the memory cell. The first circuit programs each of the more than two states into the memory cell based on the signals.
