Title: Error correction checking system of memory provided with ecc
Inventor: IWATA KATSUYUKI
IPC: G06F12/16
Filed: 1983-04-28
Abstract: PURPOSE:To shorten a check time for processing the error of a memory by providing a means for writing a data containing a correctable artificial error at the time of write, correcting this error at the time of read-out, and rewriting a correct data, and executing a check. CONSTITUTION:A data written in a buffer memory 1 is inputted from a storage data register 11, and a check bit ECC is generated by branching from each bit, added to the data and stored in the memory 1. 1-bit of this data and an output of an AND circuit 14 are inputted through an EOR circuit 15. An error generating signal is applied as one input of the circuit 14, and a rewrite signal is applied as the other input through an invertor 13. In this constitution, a check bit 5 generated by a check bit generating circuit 4 from a read-out data is different from the contents of a check bit 3 generated by a check bit generating circuit 12, therefore, a result of decoding by a decoder 7 becomes a 1-bit error which can be corrected. It is corrected and becomes a rewrite signal, and a correct data is written in the memory 1.
