description: |
|
|
The OCM supports 64-bit wide ECC functionality to detect multi-bit errors
|
|
and recover from a single-bit memory fault.On a write, if all bytes are
|
|
being written, the ECC is generated and written into the ECC RAM along with
|
|
the write-data that is written into the data RAM. If one or more bytes are
|
|
not written, then the read operation results in an correctable error or
|
|
uncorrectable error.
