ABSTRACT:
Embodiments of the present invention provide method and device for searching fixed length data. The device includes a hash operation means for operating and outputting a hash value of inputted fixed length data, a data table memory consisting of N numbers of memory banks, where N is an integer that is more than and equal to 2, the data table memory for storing a data table holding a large number of fixed length data, a pointer table memory for storing a memory pointer table holding a memory address at which each fixed length datum is stored with the hash value as an index, and a comparison means for simultaneously comparing a plurality of fixed length data stored at the same memory address in the N numbers of memory banks with a single fixed length datum inputted to the hash operation means, the comparison means for outputting results of the comparison.
