Thanks a lot for inputs
normally we will do pattern check on RAM after every initialization, to check any RAM failures. instead of pattern check either ECC will check ram failures after every initialization.
No need to implement pattern check ??
The initialization after POR only initializes the SRAM to zeros along with the ECC information.
But it does not check for failures during the initialization.
During an aligned memory write, no ECC check is performed.
The ECC check is performed when the SRAM is read.
It depends on your application requirements.
