  The open-source NVK driver in Mesa has gotten quite a lot of attention over the past couple years, unfortunately it will probably never be competitive with the proprietary driver on older hardware (Pascal (10xx series) and older) because those GPUs require a proprietary firmware blob in order to increase the GPU clock speeds.

  RAM just means the access latency is more or less the same regardless of which particular bit is being addressed, unlike e.g. a spinning rust drive where you have to wait for the platter to rotate into position under the drive head. EEPROM is also RAM - it’s memory and you can read any particular bit in constant time.

  They probably mean EC code? That said, you can use checksums to “correct” errors if you have redundant copies of the data (by reading from the other copy if one copy has a bad checksum)
