Abstract
PURPOSE: To simplify the management of buffer memroy, by compulsively introducing errors in the stored information written in the buffer memory, when errors are present in the data read out from the main memory unit.
CONSTITUTION: In the data transfer from the main memory unit M.MET to the buffer mrmory 2, the data section of the information 1 is shared into a given number of bytes at the information 5, and the parity bit P is produced with the parity producing circuits 6-0W6-7 based on the byte data shared to form one byte's share. Further, the syndrome is produced 7 based on the information 1 and error is judged 8. Further, in case of one-bit error, the output of the circuit 8 makes bit-inversion for an arbitrary one bit in the information 5 compulsively to produce the information 3 in error correction. In case of two-bit error, the error which can all invert the partity bit in the information 5 with the output of the circuit 9, is introduced to constitute the information 3.
