Parity Backed RAM

Hi guys,

The i.MX RT range appears well suited for industrial application and I'm eager to use it in a data logging project, however, my data logging will track accumulated values over a long period of time and so it's important to me that these values remain accurate.

Some competitor products offer parts of RAM that are parity backed to ensure their integrity or at the very least detection of an error. I can't find any mention in the datasheets of the i.MX RT series but just thought I'd ask if parity checking in RAM is supported? As manufacturers don't always think to list this information. If not, this would potentially be a good feature to see in future silicon.

Many thanks

Unfortunately i.MX RT does not support ECC RAM. Its SDRAM interface supports only 8-bit and 16-bit modes.

Have a great day,
Victor

Hi Victor, I was referring to the internal RAM, does this have any support?

i.MX RT does not support parity check on internal RAM too.
Sorry for the inconvenience.
