00:00:00.680 --> 00:00:07.439
it seems like 3D is always being turned

00:00:03.760 --> 00:00:10.559
into this exciting selling point we've

00:00:07.439 --> 00:00:12.920
seen it with movies video games movies

00:00:10.559 --> 00:00:18.400
again and any number of other random things as well and as tired as it is

00:00:16.160 --> 00:00:23.199
Samsung and the rest of the flash industry are using this classic

00:00:20.920 --> 00:00:28.560
marketing buzzword for their new Nan flash technology design which hold on a

00:00:25.960 --> 00:00:32.439
second wait don't go it might actually be worth paying attention to this time

00:00:30.720 --> 00:00:38.120
all right so let's get started now historically The nand Flash that lets

00:00:35.000 --> 00:00:40.960
your SD cards USB drives and ssds or

00:00:38.120 --> 00:00:46.120
solid state drives actually store data so quickly and reliably has been made up

00:00:43.600 --> 00:00:51.879
of memory cells strung horizontally along a flat plane and the primary way

00:00:49.039 --> 00:00:57.280
that we would reduce the physical size of it uh limiting production costs or

00:00:54.840 --> 00:01:03.039
increase the number of cells improving storage space and or performance was by

00:01:00.640 --> 00:01:08.560
squeezing the space between these lines ever and ever closer but unfortunately

00:01:06.560 --> 00:01:13.200
quantum physics is a bit of a Harsh Mistress and shrinking all these

00:01:10.920 --> 00:01:17.520
elements past a certain point with modern materials anyway uh when we're

00:01:15.520 --> 00:01:22.759
quickly approaching by the way creates little issues like corruption or

00:01:20.040 --> 00:01:28.079
complete and total data loss caused by signals jumping between neighboring

00:01:24.920 --> 00:01:30.240
cells at random so while we were on our

00:01:28.079 --> 00:01:33.360
way towards this inevitable outc come like an asteroid headed towards the

00:01:31.720 --> 00:01:38.159
Pacific Ocean which would create a tidal wave 3 miles high some bright rough neck

00:01:36.399 --> 00:01:43.000
had been thinking of a way to turn the old design model on its side to save us

00:01:41.600 --> 00:01:47.399
which is actually pretty much the solution in a nutshell you see a typical

00:01:45.119 --> 00:01:53.119
Nan cell looks a little something like this consisting of an electrical source

00:01:49.920 --> 00:01:55.960
drain and both float and control Gates

00:01:53.119 --> 00:02:00.880
all set over semiconductive silicon when the float gate becomes highly charged it

00:01:58.399 --> 00:02:05.240
causes electrons to spill into and become trapped in a layer of oxide this

00:02:03.360 --> 00:02:09.160
in turn causes the charge to build up inside the float gate until it meets a

00:02:06.759 --> 00:02:14.000
required voltage thresold and is washed out the drain this would be considered

00:02:11.319 --> 00:02:17.840
the binary one state which some viewers May recognize as being a bit backwards

00:02:15.879 --> 00:02:23.000
from traditional CPU transistor and bit code relationships well anyway in the

00:02:20.160 --> 00:02:28.200
new threedimensional models they take a typical style line segment and bend it

00:02:25.680 --> 00:02:33.400
into a square U shape at the middle then flip it vertically this has allowed for

00:02:30.560 --> 00:02:37.680
engineers to implant several vertical cell segments in the same width of a

00:02:35.519 --> 00:02:42.640
traditional horizontal one or in other words we can drastically increase

00:02:39.959 --> 00:02:46.920
storage capacities and access speeds without the drawbacks that come with

00:02:44.800 --> 00:02:50.000
further miniaturization of the components so at this point you're

00:02:48.720 --> 00:02:54.920
probably waiting for me to say something like sounds great right too bad it's

00:02:52.400 --> 00:02:58.920
horribly expensive well but uh that would actually be dead wrong this time

00:02:56.640 --> 00:03:04.000
you see the main attraction to both manufacturers and consumers alike is

00:03:01.800 --> 00:03:10.360
that this process actually allows the cost per bit to go down as sizes

00:03:07.599 --> 00:03:15.239
increase you see the old flat chips required heavy amounts of lithography

00:03:12.840 --> 00:03:20.200
which is the altering and shaping of materials whereas the new full-bodied

00:03:17.840 --> 00:03:26.040
ones obtain their properties mostly through the more basic deposition or

00:03:22.560 --> 00:03:28.400
building process so as it turns out less

00:03:26.040 --> 00:03:33.120
really is more in this case so you can rest easy knowing that the days of

00:03:30.680 --> 00:03:36.360
affordable and expandable memory are right around the corner and we have

00:03:34.519 --> 00:03:42.400
absolutely nothing to worry about going forward well that is until we run into

00:03:40.040 --> 00:03:47.360
the exact same problem again once we've used up all the extra space we freed up

00:03:44.360 --> 00:03:49.840
by flipping everything vertically so

00:03:47.360 --> 00:03:55.599
there's that speaking of that uh buying razors at the store

00:03:53.360 --> 00:04:00.519
that doesn't seem like a very good idea at all maybe there's a less expensive

00:03:58.079 --> 00:04:05.480
and more efficient way to buy things to shave your face that you can use all

00:04:02.840 --> 00:04:10.040
that extra space that you freed up on your SSD which okay this Segway made no

00:04:08.319 --> 00:04:14.480
sense whatever it doesn't matter Dollar Shave Club is what it's all about right

00:04:12.680 --> 00:04:18.040
now get razors and other bathroom supplies shipped directly to your door

00:04:16.239 --> 00:04:22.479
for only a few bucks a month we're talking razors Dr Carver shave butter

00:04:20.880 --> 00:04:26.880
there one wipe Charlie's peppermint scented butt wipes from in which by the

00:04:24.639 --> 00:04:30.240
way I would have been pretty glad to have at in some of those bathrooms in

00:04:29.000 --> 00:04:34.240
Southeast Asia and I totally forgot to take a pack of

00:04:32.880 --> 00:04:38.160
them with me which would have been a great idea they've also got their post

00:04:35.960 --> 00:04:42.000
shave moisturizer and travel sizes of some of those things as well they've got

00:04:39.520 --> 00:04:48.720
a variety of Razor Styles all the way up to the six blade executive and it's just

00:04:45.720 --> 00:04:50.720
pretty simple I guess the concept is you

00:04:48.720 --> 00:04:54.680
sign up for the club they ship you the razors your face looks good your wallet

00:04:53.120 --> 00:04:58.240
feels good and it's dollarshaveclub.com Linus if all of that

00:04:56.560 --> 00:05:04.639
sounded good to you it's available in the US Canada Australia and New Zealand

00:05:02.960 --> 00:05:07.560
so thank you guys for watching like this video if you liked it dislike it if you

00:05:06.160 --> 00:05:10.520
thought it sucked leave a comment if you have a suggestion for a future fastest

00:05:09.160 --> 00:05:16.880
Possible episode just like this one and as always don't forget to subscribe and
