Protection of data on a data path in a memory system

Abstract:

Some examples herein provide for protection of data on a data path in a memory system in an integrated circuit. In an example, an integrated circuit includes a bit checker circuit, an Error Correcting Code (ECC) encoder circuit, an ECC decoder circuit, and a check bit generation circuit. The bit checker circuit is configured to check write data based on write-path check bit(s). The ECC encoder circuit is configured to generate a write encoded ECC value based on the write data. The write encoded ECC value is to be written to the memory with the write data. The ECC decoder circuit is configured to decode a read encoded ECC value and check read data based on the read encoded ECC value. The read encoded ECC value and read data are read from the memory. The check bit generation circuit is configured to generate read-path check bit(s) from the read data.
