Abstract
A method and apparatus for storing pattern matching data and a pattern matching method using the method and apparatus are provided. The method of storing original data for pattern matching in a pattern matching apparatus includes: dividing the original data into segments of a predetermined size; performing a hash operation on each of the divided segments; determining whether or not the hash operation value of each segment causes a hash collision with a hash operation value stored in a first external memory disposed outside the pattern matching apparatus; and controlling the hash operation value of each segment determined not to cause a hash collision to be stored in the first external memory. According to the method and apparatus, the original data desired to be used for pattern matching can be stored at a faster speed in a pattern matching data storing apparatus.
