So ; I didnt understand what does mean in the red circles ?

256x8 = 256 cells which can hold 8 bits each.
02A07 - no idea

I can't find anything else on rear numbers. Obviously some of the figures are a date
Searching C1244 just leads to Toyota which is way off.

I wouldn't search HI Level Ram as it appears its site tries to send you files, they were all blocked by my anti virus.
