But I read it in multiple Mac-specific websites. The integration seems to be so tight that the entire memory structure is dynamically allocated as the various functions need it. So any given memory location might be RAM, or Storage, or cache, or scratch, at any time. The firmware of the SoC seems to have some ability to adjust and block out small areas of failure, but if there is any major issue that tight integration then starts to bite because the CPU or GPU may demand a space, be assigned to one that has failed and therefore crash. So, if the SoC has the equivalent of an SSD failure, the system is dead. At least from the reading I have done. I'll see if I can locate the various places I have read that again.</p></blockquote><p></p>
