In its financial report, Macronix said ROM fell to 5 percent of its sales. A year ago, it was at 26 percent. Macronix’s chairman noted that capacity is limited and is going to NOR and eMMC memory chips instead.

Analyst David Gibson, who shared the news, pointed out that Macronix isn’t Nintendo’s only game memory card maker. In other words, collectors don’t have to worry yet about physical games being phased out – at least not yet.

Nintendo still has other chip suppliers, but this is a noteworthy development I think.
