Abstract: A level-shifter circuit receives one or more input signals in an input level domain and includes provides at an output node an output signal in an output level domain shifted with respect to the input level domain. The circuit includes output circuitry including a first drive node and a second drive node that receive first and second logical signals so that the output signal has a first output level or a second output level in the output level domain as a function of at least one of the first and second logical signals. The circuit includes first and second shift capacitors coupled to the first and second drive nodes as well as capacitor refresh circuitry.

Abstract: In a non-volatile memory device, a memory sector is provided. The memory sector includes a plurality of tiles arranged horizontally. Each tile includes a plurality of memory cells arranged in horizontal word lines and vertical bit lines. A pre-decoder is configured to receive a set of encoded address signals to produce pre-decoding signals. A central row decoder is arranged in line with the plurality of tiles, receives the pre-decoding signals and produces level-shifted pull-up and pull-down driving signals for driving the word lines. First buffer circuits are arranged on a first side of each tile. Each of the first buffer circuits is coupled to a respective word line, receives a level-shifted pull-up driving signal and a level-shifted pull-down driving signal, and selectively pulls up or pulls down the respective word line as a function of the values of the received signals.
