    Is there any need to do memory check in MCU before beginning operation?
    I had read on new MCU its not needed?
    is there any example code specific to cortex-m3?

    What action will you take if there is a problem? Depending on the answer you then ask if partial or restricted operation is better than no operation at all.

    If ram failure, then no operation.

    I would do what you can in the shortest amount of time possible. If you delay your startup for more than a couple of hundred milliseconds then people will develop a negative impression of the product. If you are that worried about memory integrity I would test the memory continuously during operation. Of course a hard shutdown in the middle of a process might have other negative consequences.

    I can't remember seeing anything useful in my searches.
