Abstract

PURPOSE: To enable to write-in the data information and miscorrection information to the memory element of the memory circuit more correctly, by providing the miscorrection instructinf information source and miscorrection information control circuit with the memory circuit having error correction function.
CONSTITUTION: To the mis-correction information control circuit U, the misdetection information SK from the misdetection circuit K is input, and the output of the circuit U is controlled with the information from the miscorrection instructing information source. If the information SV from the miscorrection instructing information source. If the information SV is 1, the mis-detection information SU is given to the miscorrection circuit L from the circuit U, and the data information SL1WSL4 corrected with error is obtained from the circuit L. Further, if the information SV is 0, the information obtained respectively from the data information and miscorrection information circuit and mis-detection information generating circuit is written in the memory element of the memory circuit as the error correction information. With this state, when information is obtained from the data information source, the data information and miscorrection information is written in the memory element, this information can be written in the memory element with much correction.
