1
00:00:00,680 --> 00:00:07,439
it seems like 3D is always being turned

2
00:00:03,760 --> 00:00:10,559
into this exciting selling point we've

3
00:00:07,439 --> 00:00:12,920
seen it with movies video games movies

4
00:00:10,559 --> 00:00:18,400
again and any number of other random things as well and as tired as it is

5
00:00:16,160 --> 00:00:23,199
Samsung and the rest of the flash industry are using this classic

6
00:00:20,920 --> 00:00:28,560
marketing buzzword for their new Nan flash technology design which hold on a

7
00:00:25,960 --> 00:00:32,439
second wait don't go it might actually be worth paying attention to this time

8
00:00:30,720 --> 00:00:38,120
all right so let's get started now historically The nand Flash that lets

9
00:00:35,000 --> 00:00:40,960
your SD cards USB drives and ssds or

10
00:00:38,120 --> 00:00:46,120
solid state drives actually store data so quickly and reliably has been made up

11
00:00:43,600 --> 00:00:51,879
of memory cells strung horizontally along a flat plane and the primary way

12
00:00:49,039 --> 00:00:57,280
that we would reduce the physical size of it uh limiting production costs or

13
00:00:54,840 --> 00:01:03,039
increase the number of cells improving storage space and or performance was by

14
00:01:00,640 --> 00:01:08,560
squeezing the space between these lines ever and ever closer but unfortunately

15
00:01:06,560 --> 00:01:13,200
quantum physics is a bit of a Harsh Mistress and shrinking all these

16
00:01:10,920 --> 00:01:17,520
elements past a certain point with modern materials anyway uh when we're

17
00:01:15,520 --> 00:01:22,759
quickly approaching by the way creates little issues like corruption or

18
00:01:20,040 --> 00:01:28,079
complete and total data loss caused by signals jumping between neighboring

19
00:01:24,920 --> 00:01:30,240
cells at random so while we were on our

20
00:01:28,079 --> 00:01:33,360
way towards this inevitable outc come like an asteroid headed towards the

21
00:01:31,720 --> 00:01:38,159
Pacific Ocean which would create a tidal wave 3 miles high some bright rough neck

22
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

23
00:01:41,600 --> 00:01:47,399
which is actually pretty much the solution in a nutshell you see a typical

24
00:01:45,119 --> 00:01:53,119
Nan cell looks a little something like this consisting of an electrical source

25
00:01:49,920 --> 00:01:55,960
drain and both float and control Gates

26
00:01:53,119 --> 00:02:00,880
all set over semiconductive silicon when the float gate becomes highly charged it

27
00:01:58,399 --> 00:02:05,240
causes electrons to spill into and become trapped in a layer of oxide this

28
00:02:03,360 --> 00:02:09,160
in turn causes the charge to build up inside the float gate until it meets a

29
00:02:06,759 --> 00:02:14,000
required voltage thresold and is washed out the drain this would be considered

30
00:02:11,319 --> 00:02:17,840
the binary one state which some viewers May recognize as being a bit backwards

31
00:02:15,879 --> 00:02:23,000
from traditional CPU transistor and bit code relationships well anyway in the

32
00:02:20,160 --> 00:02:28,200
new threedimensional models they take a typical style line segment and bend it

33
00:02:25,680 --> 00:02:33,400
into a square U shape at the middle then flip it vertically this has allowed for

34
00:02:30,560 --> 00:02:37,680
engineers to implant several vertical cell segments in the same width of a

35
00:02:35,519 --> 00:02:42,640
traditional horizontal one or in other words we can drastically increase

36
00:02:39,959 --> 00:02:46,920
storage capacities and access speeds without the drawbacks that come with

37
00:02:44,800 --> 00:02:50,000
further miniaturization of the components so at this point you're

38
00:02:48,720 --> 00:02:54,920
probably waiting for me to say something like sounds great right too bad it's

39
00:02:52,400 --> 00:02:58,920
horribly expensive well but uh that would actually be dead wrong this time

40
00:02:56,640 --> 00:03:04,000
you see the main attraction to both manufacturers and consumers alike is

41
00:03:01,800 --> 00:03:10,360
that this process actually allows the cost per bit to go down as sizes

42
00:03:07,599 --> 00:03:15,239
increase you see the old flat chips required heavy amounts of lithography

43
00:03:12,840 --> 00:03:20,200
which is the altering and shaping of materials whereas the new full-bodied

44
00:03:17,840 --> 00:03:26,040
ones obtain their properties mostly through the more basic deposition or

45
00:03:22,560 --> 00:03:28,400
building process so as it turns out less

46
00:03:26,040 --> 00:03:33,120
really is more in this case so you can rest easy knowing that the days of

47
00:03:30,680 --> 00:03:36,360
affordable and expandable memory are right around the corner and we have

48
00:03:34,519 --> 00:03:42,400
absolutely nothing to worry about going forward well that is until we run into

49
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

50
00:03:44,360 --> 00:03:49,840
by flipping everything vertically so

51
00:03:47,360 --> 00:03:55,599
there's that speaking of that uh buying razors at the store

52
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

53
00:03:58,079 --> 00:04:05,480
and more efficient way to buy things to shave your face that you can use all

54
00:04:02,840 --> 00:04:10,040
that extra space that you freed up on your SSD which okay this Segway made no

55
00:04:08,319 --> 00:04:14,480
sense whatever it doesn't matter Dollar Shave Club is what it's all about right

56
00:04:12,680 --> 00:04:18,040
now get razors and other bathroom supplies shipped directly to your door

57
00:04:16,239 --> 00:04:22,479
for only a few bucks a month we're talking razors Dr Carver shave butter

58
00:04:20,880 --> 00:04:26,880
there one wipe Charlie's peppermint scented butt wipes from in which by the

59
00:04:24,639 --> 00:04:30,240
way I would have been pretty glad to have at in some of those bathrooms in

60
00:04:29,000 --> 00:04:34,240
Southeast Asia and I totally forgot to take a pack of

61
00:04:32,880 --> 00:04:38,160
them with me which would have been a great idea they've also got their post

62
00:04:35,960 --> 00:04:42,000
shave moisturizer and travel sizes of some of those things as well they've got

63
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

64
00:04:45,720 --> 00:04:50,720
pretty simple I guess the concept is you

65
00:04:48,720 --> 00:04:54,680
sign up for the club they ship you the razors your face looks good your wallet

66
00:04:53,120 --> 00:04:58,240
feels good and it's dollarshaveclub.com Linus if all of that

67
00:04:56,560 --> 00:05:04,639
sounded good to you it's available in the US Canada Australia and New Zealand

68
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

69
00:05:06,160 --> 00:05:10,520
thought it sucked leave a comment if you have a suggestion for a future fastest

70
00:05:09,160 --> 00:05:16,880
Possible episode just like this one and as always don't forget to subscribe and
