ABSTRACT:
An end-of-count detecting device for nonvolatile memories, comprising a decoder in the form of a wired OR structure of a number of transistors of the same type, the gate terminals of which are fed with a count signal generated by a counter element and having a predetermined end-of-count value to be detected. A load, which may be static, pseudo-dynamic or dynamic, is provided between the common node of the decoder transistors and a reference potential line; and the decoder output formed by the common node assumes a different logic level according to whether or not the end-of-count value coded by the wired OR structure is reached. A number of wired OR structures may be arranged side by side with an array of transistors for detecting a number of end-of-count values of the same counter element.
