The search memory includes an input control section, N search units, and N first selectors. The input control section receives N (N: two or more) search data that are parallelly inputted. The N first selectors are respectively disposed in association with the N search units to select two search data from the N search data. The search units each include multiple search blocks and M second selectors. The M second selectors select one of two search data selected by the first selectors. For at least one of the N search units, allocation is performed so that two types out of N types of entry data respectively associated with the N search data are respectively stored in the search blocks.
