it seems like 3D is always being turned
into this exciting selling point we've
seen it with movies video games movies
again and any number of other random things as well and as tired as it is
Samsung and the rest of the flash industry are using this classic
marketing buzzword for their new Nan flash technology design which hold on a
second wait don't go it might actually be worth paying attention to this time
all right so let's get started now historically The nand Flash that lets
your SD cards USB drives and ssds or
solid state drives actually store data so quickly and reliably has been made up
of memory cells strung horizontally along a flat plane and the primary way
that we would reduce the physical size of it uh limiting production costs or
increase the number of cells improving storage space and or performance was by
squeezing the space between these lines ever and ever closer but unfortunately
quantum physics is a bit of a Harsh Mistress and shrinking all these
elements past a certain point with modern materials anyway uh when we're
quickly approaching by the way creates little issues like corruption or
complete and total data loss caused by signals jumping between neighboring
cells at random so while we were on our
way towards this inevitable outc come like an asteroid headed towards the
Pacific Ocean which would create a tidal wave 3 miles high some bright rough neck
had been thinking of a way to turn the old design model on its side to save us
which is actually pretty much the solution in a nutshell you see a typical
Nan cell looks a little something like this consisting of an electrical source
drain and both float and control Gates
all set over semiconductive silicon when the float gate becomes highly charged it
causes electrons to spill into and become trapped in a layer of oxide this
in turn causes the charge to build up inside the float gate until it meets a
required voltage thresold and is washed out the drain this would be considered
the binary one state which some viewers May recognize as being a bit backwards
from traditional CPU transistor and bit code relationships well anyway in the
new threedimensional models they take a typical style line segment and bend it
into a square U shape at the middle then flip it vertically this has allowed for
engineers to implant several vertical cell segments in the same width of a
traditional horizontal one or in other words we can drastically increase
storage capacities and access speeds without the drawbacks that come with
further miniaturization of the components so at this point you're
probably waiting for me to say something like sounds great right too bad it's
horribly expensive well but uh that would actually be dead wrong this time
you see the main attraction to both manufacturers and consumers alike is
that this process actually allows the cost per bit to go down as sizes
increase you see the old flat chips required heavy amounts of lithography
which is the altering and shaping of materials whereas the new full-bodied
ones obtain their properties mostly through the more basic deposition or
building process so as it turns out less
really is more in this case so you can rest easy knowing that the days of
affordable and expandable memory are right around the corner and we have
absolutely nothing to worry about going forward well that is until we run into
the exact same problem again once we've used up all the extra space we freed up
by flipping everything vertically so
there's that speaking of that uh buying razors at the store
that doesn't seem like a very good idea at all maybe there's a less expensive
and more efficient way to buy things to shave your face that you can use all
that extra space that you freed up on your SSD which okay this Segway made no
sense whatever it doesn't matter Dollar Shave Club is what it's all about right
now get razors and other bathroom supplies shipped directly to your door
for only a few bucks a month we're talking razors Dr Carver shave butter
there one wipe Charlie's peppermint scented butt wipes from in which by the
way I would have been pretty glad to have at in some of those bathrooms in
Southeast Asia and I totally forgot to take a pack of
them with me which would have been a great idea they've also got their post
shave moisturizer and travel sizes of some of those things as well they've got
a variety of Razor Styles all the way up to the six blade executive and it's just
pretty simple I guess the concept is you
sign up for the club they ship you the razors your face looks good your wallet
feels good and it's dollarshaveclub.com Linus if all of that
sounded good to you it's available in the US Canada Australia and New Zealand
so thank you guys for watching like this video if you liked it dislike it if you
thought it sucked leave a comment if you have a suggestion for a future fastest
