[sci.electronics] American DRAMs

An article <1988Mar17.195328.12277@gpu.utcs.toronto.edu> (wow!) by

Actually the US producers who_sell_externally (i.e. excluding IBM)
are AT&T, Texas Instruments, and Micron Technology.  Motorola imports
wafers from Toshiba, tests the dice, packages the good 'uns, and sells
them under the Motorola label.  Similarly, Intel has an agreement to
do the same thing with Samsung dRAMS (from South Korea).  T.I. has
two dRAM fabs, one in Miho, Japan and one in Richardson, Texas.  T.I.
builds their own designs, which originate in Houston.

Well, not completely correct.  All three US companies, AT&T, TI, and
Micron, have designed and built working 1Megabit dRAMS.  It's just that
these companies aren't building them in high volume and selling them yet.
Partly it's cuz the US parts were later than the Japanese producers', and
partly it's cuz one can make mucho revenue building the (simpler) 256K
device for which demand exceeds supply.

Also, there are (were) a few more American companies who designed and
built working 1Megabit dRAMS and then decided not to sell them ---
the perceived cost of the submicron fabs was too high.  Intel, Mostek,
and Inmos {um, not really a US company now that I think about it},
all had working 1Megabits that they didn't take into production.
AMD also had a 1Megabit program but I don't know whether they built
working die.

In any case, no "US DRAM conspiracy" exists, pitting evil American
mfrs who deliberately restrict capacity, against helpless consumers
who are forced to purchase huge volumes of chips at artificially high
prices.  The sad fact is that American companies don't have the
stomach for the roller-coaster DRAM market, nor will their stockholders
permit the huge investments necessary to participate in the DRAM
crapshoot {I mean, um, DRAM market.  Yeah.}
