ABSTRACT:
A coding device including an array of multibit registers, each being composed of a plurality of programmable nonvolatile memory cells connected to an OR configuration to a common sensing line of the register to which a single reading circuit is associated. A first, select/enable bus (SELbus) controls the connection of only one at a time of said programmable memory cells to said common sensing line of each multibit register. To each wire of a second, configuring bus (CODE bus) are connected in common the current terminals of as many programming transistors as the memory cells that compose each register, and to each wire of a third, contingently programming bus (PG bus) are connected the gates of the programming transistors of memory cells of the same order of said registers.
