Abstract
A range check array structure for searching and comparing external data from an external search data key is disclosed. The structure has data storage means with at least one of an upper limit field, and a lower limit field, and one or more bit lines running therethrough for transmitting an input data word for comparison with the stored data word range. The input data word being compared with a respective stored data word to detect a match that is indicated along a match line by the check array structure. The check array structure further includes a range match detection means connected to the match line to determine the match or mismatch of the applied data stream with the stored data in each range check cell.
