Abstract
A content addressable memory array includes an array of M words containing bits configured in N bits for each word. One of the bits in each of the words is a settable skip bit, and during a search of the memory array, the array is examined to detect the presence therein of skip bits. If a skip bit is detected in any one of the words, that word containing the detected skip bit is eliminated from the search. Each word in the array also contains an empty bit which is used to indicate an empty word location in the array. When all empty bits are set, the array is automatically reset to empty or zero.
