ABSTRACT:
A first-in first-out memory device for storing a series of numeral signals includes a comparator for comparing each input numeral signal with a preselected numeral signal, and for producing a matching signal when the input numeral signal is the same as the preselected numeral signal, and an unmatching signal when the input numeral signal is not the same as the preselected numeral signal. An up-counter counts the number of repetition of the matching signal. When the input numeral signal is other than the preselected numeral signal, a tag signal representing the numeral signal is produced and, at the same time, a data signal representing the value of the numeral signal is produced. When the input numeral signal is the preselected numeral signal, such as zero, a tag signal representing repetition number signal is produced and, at the same time, the data signal representing the number of repetition of zeros is produced. Such a pair of tag signal and data signal is stored in a memory.
