Samsung has production problems with its 68 nm RAM ?

During April, it was learned that Hynix encountered production problems with its memory chips engraved in 66 nm, leading them to throw a considerable part of the months production into the dustbin.
Samsung apparently has similar problems and has instabilities in the production of chips engraved in 68 nm. Thus, the equivalent of 80 million chips of 128 MB may have been rejected during the qualification tests.
Even though this is a bad news for Samsung, it should not affect the strong sales of these memory chips, the market is not particularly saturated in this lean period.
This could change with the back-to-school period and in the end of year period if the production problems are not solved by then.
