When DigiTimes published a rumor earlier this month saying Samsung was having issues making enough mobile RAM chips for the Galaxy S4, the report was dismissed. Because let’s face it, DigiTimes is usually right only 50% of the time about anything they put up on their website.

But now there’s a new report out, from Bloomberg of all sources, that says what DigiTimes said almost three weeks ago:

“For the first time, the company that makes more than half the world’s mobile DRAM chips may buy them from SK Hynix, said Shin Jong Kyun, head of Suwon, South Korea-based Samsung’s mobile business.”

It’s not as if Samsung wasn’t prepared. They’ve been spending about $1 billion a month every month for the past two years to increase their mobile DRAM output, but it’s simply not enough. Samsung keeps saying that demand for the GS4 is overwhelming, without providing any actual numbers, but pretty soon we might get a glimpse as to what’s happening.

Remember, the phone goes on sale in multiple countries tomorrow.
