Re: Program a microcontroller over its physical memory limit
it means , say , a uc has 64k flash inside . but , they sell it as 8k or 16k etc .
if that is true then all uc of same should have same die area
irrespective of program mem (or ram) size.
bigger here may mean reduced yield , which i dont think , they will do that .
methodology of graphic card may not be applicable here.
earlier what they used is :
make a uc , say , 4k prog mem .
if in QC , the mem part fails , then they disable the mem and sell it
as romless version.
the same here , mem will be enabled for the addresses it what was meant for.
but the current practice in fab can be known from other posters of forum who knew the current situation.
