Abstract

PURPOSE: To obtain a syndrome generating circuit for error correction code generation which operates through binary logic, by composing the syndrome code generating circuit of several equal logic blocks.
CONSTITUTION: Several logic blocks are provided which are provided on the same substrate with the syndrome generating method generating the error-correction-code generating syndrome by at least one section 21 of input data and correction code 23, parity checking method using section 21 and corresponding parity code 24, and switching method sending out the correction code to the syndrome generating method when the correction code is supplied as a check code and the parity code to the parity checking method when the parity code is supplied. Then, the syndrome is generated from the syndrome generating method of either 1st or 2nd logic block.
