Abstract
In a charge trapping memory architecture for virtual ground with interconnects () that are present parallel to the word lines () and STI isolations () that are present parallel to the bit lines (), provision is made of STI isolations () that are widened for division into slices. Instead of this, the interconnects present below a bit line may be omitted or two mutually adjacent bit lines () may be wired up in such a way that the memory transistors present between them operate only in the dummy mode.
