  • Patent number: 4757522
    Abstract: In a counting circuit having non-volatile electrically erasable memory elements and a plurality of similar counters each representing one place of the count, respective memory elements of suitable capacity are associated with the counters. Low value counters can be connected cyclically to each other via their counting inputs and transfer outputs. Their association with the other places of a count is changed as a function of the count of the highest-value place. In this way, the result is obtained, without additional expense for memory, that the individual memory elements are erased equally frequently during the life of the counting circuit.
