Sure!
You'll probably find that the absolute cheapest memory you can buy
doesn't last as long or perform as well as the more expensive stuff.
Back in school, some classmates and I went on a tour of NEC in
Roseville. The tour guide (a former chemical engineering student)
mentioned, in front of a neat laser that processed memory chips, that
NEC's chips have redundant wires, so if one wire fails, the chip can
still work. You might not find that feature on cheaper chips.
This is probably bad advice. One of the more important influences on
the price of a chip is the volume being produced. More expensive chips
remain available largely because it is cheaper to keep on using a more
expensive chip than it is to redesign and re-layout a printed circuit
board to take advantage of a chip that didn't go into production until
after the board was designed.
So the equation of higher price with better quality is rarely - if
ever - valid.
And NEC was spending money on putting in redundant connections because
a significant proportion of the chips coming off the end of their
production line didn't work, and some of those non-working chips could
be made to work by using one of the "redundant" connections.
Once they'd got their production process under better control, most of
the chips produced would have worked first time, and they'd have
stopped wasting money on the redundant connections (which never did a
thing for the end-user anyway).
