Re: memory question (hardware)

Thanks for the responses.

What is the engineering challenge of having more memory in a single die? I expect latency would be a issue. Also, as Brad mentioned greater risk of failure.

Any thing else?

Obviously we can't open up the sticks and look at the chips, but the
usual answer is that the 2G used "the older" technology and the 4G
used the "newer" technology and the chip vendor is trying to recoup
development costs.  As the "newer" technology becomes the "older"
technology the cost will go down.  With Moore's "law" this gives the
chip vendor about 18 months to recoup most of the development costs
and some profit.
