    摘要: A compact, low-power, asynchronous, resistor-based memory read circuit includes a memory cell having a plurality of consecutive memory states, each of said states corresponding to a respective output voltage. A sense amplifier reads the state of the memory cell. The sense amplifier includes a voltage divider configured to receive the output voltage of the memory cell and to output a settled voltage an amplifier having a voltage threshold between the settled voltages associated with two of said consecutive memory states, configured to discriminate between said two consecutive memory states.

    摘要: Embodiments of the present invention provide a device comprising a plurality of phase change memory cells, a word line, and a plurality of bit lines. Each phase change memory cell is coupled to a corresponding transistor. Each transistor is coupled to the word line. Each bit line is coupled to a phase change memory cell of the device. The device further comprises a programming circuit configured to program at least one phase change memory cell to the SET state by selectively applying a two-stage waveform to the word line and the bit lines of the device. In a first stage, a first predetermined low voltage and a first predetermined high voltage are applied at the word line and the bit lines, respectively. In a second stage, a second predetermined high voltage and a predetermined voltage with decreasing amplitude are applied at the word line and the bit lines, respectively.
