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.
