Abstract
A method of storing data in a memory circuit of an Aho-Corasick type character recognition automaton recognizes character strings by implementing successive transitions in a tree of nodes stored in a memory. Each node corresponds to a state of the automaton and to a recognition of a sequence of the character string. Each node is associated with a transition vector serves to determine the destination node or nodes of a transition. For storage of the data, a test is performed to find out whether transition vectors point to common destination addresses. The transition vectors are combined if the addresses to which the vectors point are separate by formulating a combination vector and the nodes are stored at the memory addresses pointed at by the combination vector.
