When you say "in case of LPDDR" below, you should also change this
line to take other cases into account. Maybe the best way to write
this would be something like:

...or generated strings of a memory type dependent form. For LPDDR
types, that form is lpddrX-YY,ZZZZ where X is [...same text...]. For
DDR types, that form is ddrX-YY,ZZZZZ... where X is [...new definition
for DDR types, based on what's available in SPD...].

If this doesn't exist for DDR, then rather than "in case of LPDDR"
this should probably say something like "LPDDR only"?

Can you list here where in SPD density and I/O width are stored for
the various DDR types?
