Abstract
PURPOSE:To reduce the scale of a soft error correcting circuit by using one of two system memories to correct the multiple errors. CONSTITUTION:When the data 2 read out of a memory group 1 has an error, an error correcting circuit 3 corrects a single error and delivers the error correction output 4. Then an error detecting pulse 5 is supplied to the group 1. In this case, the data input of the group 1 is turned into the data output 8 of a memory group 7. Then an error non-detecting pulse 6 is supplied to the group 7 from the circuit 3 in case no error is detected at the circuit 3 where the correct data is written again. The memory group 7 uses the output 4 as the data input and writes data again by the pulse 6.
