it seems like 3D is always being turned
0:03
into this exciting selling point we've
0:07
seen it with movies video games movies
0:10
again and any number of other random things as well and as tired as it is
0:16
Samsung and the rest of the flash industry are using this classic
0:20
marketing buzzword for their new Nan flash technology design which hold on a
0:25
second wait don't go it might actually be worth paying attention to this time
0:30
all right so let's get started now historically The nand Flash that lets
0:35
your SD cards USB drives and ssds or
0:38
solid state drives actually store data so quickly and reliably has been made up
0:43
of memory cells strung horizontally along a flat plane and the primary way
0:49
that we would reduce the physical size of it uh limiting production costs or
0:54
increase the number of cells improving storage space and or performance was by
1:00
squeezing the space between these lines ever and ever closer but unfortunately
1:06
quantum physics is a bit of a Harsh Mistress and shrinking all these
1:10
elements past a certain point with modern materials anyway uh when we're
1:15
quickly approaching by the way creates little issues like corruption or
1:20
complete and total data loss caused by signals jumping between neighboring
1:24
cells at random so while we were on our
1:28
way towards this inevitable outc come like an asteroid headed towards the
1:31
Pacific Ocean which would create a tidal wave 3 miles high some bright rough neck
1:36
had been thinking of a way to turn the old design model on its side to save us
1:41
which is actually pretty much the solution in a nutshell you see a typical
1:45
Nan cell looks a little something like this consisting of an electrical source
1:49
drain and both float and control Gates
1:53
all set over semiconductive silicon when the float gate becomes highly charged it
1:58
causes electrons to spill into and become trapped in a layer of oxide this
2:03
in turn causes the charge to build up inside the float gate until it meets a
2:06
required voltage thresold and is washed out the drain this would be considered
2:11
the binary one state which some viewers May recognize as being a bit backwards
2:15
from traditional CPU transistor and bit code relationships well anyway in the
2:20
new threedimensional models they take a typical style line segment and bend it
2:25
into a square U shape at the middle then flip it vertically this has allowed for
2:30
engineers to implant several vertical cell segments in the same width of a
2:35
traditional horizontal one or in other words we can drastically increase
2:39
storage capacities and access speeds without the drawbacks that come with
2:44
further miniaturization of the components so at this point you're
2:48
probably waiting for me to say something like sounds great right too bad it's
2:52
horribly expensive well but uh that would actually be dead wrong this time
2:56
you see the main attraction to both manufacturers and consumers alike is
3:01
that this process actually allows the cost per bit to go down as sizes
3:07
increase you see the old flat chips required heavy amounts of lithography
3:12
which is the altering and shaping of materials whereas the new full-bodied
3:17
ones obtain their properties mostly through the more basic deposition or
3:22
building process so as it turns out less
3:26
really is more in this case so you can rest easy knowing that the days of
3:30
affordable and expandable memory are right around the corner and we have
3:34
absolutely nothing to worry about going forward well that is until we run into
3:40
the exact same problem again once we've used up all the extra space we freed up
3:44
by flipping everything vertically so
3:47
there's that speaking of that uh buying razors at the store
3:53
that doesn't seem like a very good idea at all maybe there's a less expensive
3:58
and more efficient way to buy things to shave your face that you can use all
4:02
that extra space that you freed up on your SSD which okay this Segway made no
4:08
sense whatever it doesn't matter Dollar Shave Club is what it's all about right
4:12
now get razors and other bathroom supplies shipped directly to your door
4:16
for only a few bucks a month we're talking razors Dr Carver shave butter
4:20
there one wipe Charlie's peppermint scented butt wipes from in which by the
4:24
way I would have been pretty glad to have at in some of those bathrooms in
4:29
Southeast Asia and I totally forgot to take a pack of
4:32
them with me which would have been a great idea they've also got their post
4:35
shave moisturizer and travel sizes of some of those things as well they've got
4:39
a variety of Razor Styles all the way up to the six blade executive and it's just
4:45
pretty simple I guess the concept is you
4:48
sign up for the club they ship you the razors your face looks good your wallet
4:53
feels good and it's dollarshaveclub.com Linus if all of that
4:56
sounded good to you it's available in the US Canada Australia and New Zealand
5:02
so thank you guys for watching like this video if you liked it dislike it if you
5:06
thought it sucked leave a comment if you have a suggestion for a future fastest
5:09
Possible episode just like this one and as always don't forget to subscribe and
5:12
follow and all of that good stuff
