CRC_ERROR and memory parity bits in new FPGAs

Hello, It appears that the CRC_ERROR and memory parity bits features have been introduced by Altera in the Stratix family (Cyclone too) and aren't available in older devices. Is this correct ? ...

What do you mean with memory parity? The fact that the RAM modules now feature 9k bits instead of 4k? This is not necessarily a parity bit, thus, a reliability feature. You can use this bit for whatever you want.

My understanding was that memory bytes can now come in quantas of 9-bit, which, while doesn't force us to use it for parity, nevertheless makes it simpler.
