Abstract
The semiconductor device of the present invention includes a search memory mat having a configuration in which a location with which an entry address is registered is allocated in a y-axis direction, and key data is allocated in an x-axis direction and a control circuit connected to the search memory mat. In the search memory mat, a plurality of separate memories is formed such that a region to which the key data is allocated is separated into a plurality of regions along the y-axis direction. The control circuit includes an input unit to which the key data is input, a division unit which divides the key data input to the input unit into a plurality of pieces of key data, and a writing unit which allocates each piece of divided key data by the division unit into the separate memory using the divided key data as an address.
