摘要:
An integrated circuit includes an array of phase-change memory (PCM) cells, a plurality of wordlines coupled to the array of PCM cells, and a row decoder circuit coupled to the plurality of wordlines. The row decoder circuit includes a first low voltage logic gate and a first high voltage level shifter coupled to the first low voltage logic gate. The row decoder circuit also includes a second low voltage logic gate, a second high voltage level shifter coupled to the second low voltage logic gate, and a first low voltage logic circuit coupled to the second low voltage logic gate. In addition, the row decoder circuit includes a second low voltage logic circuit coupled to the second low voltage logic gate, and a low voltage wordline driver having an input coupled to the outputs of the first and second low voltage logic gates, and an output coupled to a selected wordline.
