Product Type Nomenclature
Qimonda’s nomenclature uses simple coding combined with
some propriatory coding.
Table 34
provides examples for
module and component product type number as well as the
field number. The detailed field description together with
possible values and coding explanation is listed for modules
in
Table 35
and for components in
Table 36
.
