Abstract
A retrievable memory is provided with a priority encoder. The priority encoder is constituted by encoder units. Each of the encoder units is constituted by an inverter, N-channel MOS transistors and an AND gate. Upon receipt of a signal of H level from a matching line, the encoder unit outputs a signal of H level to a word line, and also outputs a signal of L level to a matching line active signal line MLA . Then, the encoder units respectively output signals of L level to the word lines. Consequently, even when a plurality of results of a retrieving process are obtained, it is possible to output single data.
