1
00:00:00,080 --> 00:00:06,240
if you've ever suddenly needed to buy a computer memory or an SSD there's a good

2
00:00:04,080 --> 00:00:11,519
chance you've experienced either sticker shock or a pleasant surprise when you

3
00:00:08,639 --> 00:00:16,640
looked up how much it cost indeed both RAM and the nand flash that holds the

4
00:00:13,920 --> 00:00:20,240
data inside ssds are notorious for fluctuating in price more than other

5
00:00:18,880 --> 00:00:25,199
components but why to answer we spoke with our friends at

6
00:00:23,600 --> 00:00:30,560
g-skill and we'd like to thank them for contributing their insight as it turns

7
00:00:27,359 --> 00:00:33,360
out the main reason is that both RAM and

8
00:00:30,560 --> 00:00:38,480
nand flash are commodity goods and when we say commodity we mean a good

9
00:00:35,840 --> 00:00:43,920
that can be used in many different types of markets think about corn for example

10
00:00:41,360 --> 00:00:48,879
you can eat it sure but it can also be used for everything from animal feed to

11
00:00:46,320 --> 00:00:53,120
biofuel so large amounts of it are regularly sold to many different types

12
00:00:51,760 --> 00:00:57,840
of businesses the dram and nand markets work in much

13
00:00:55,600 --> 00:01:03,760
the same way nearly all modern electronic devices everything from tvs

14
00:01:00,800 --> 00:01:10,000
to smart watches to heck even internet connected microwaves need both RAM and

15
00:01:07,040 --> 00:01:15,600
flash storage not just computers by comparison something like an x86 CPU

16
00:01:12,560 --> 00:01:18,240
from Intel or AMD is really only being

17
00:01:15,600 --> 00:01:23,119
sold to two kinds of markets system integrators like dell or hp and

18
00:01:20,880 --> 00:01:27,840
retailers like newegg and micro center you also have the fact that dram and

19
00:01:25,119 --> 00:01:32,880
nand can be shipped off more or less unchanged to these different customers

20
00:01:30,799 --> 00:01:38,320
for example the RAM that's inside your computer is not all that dissimilar from

21
00:01:35,600 --> 00:01:43,680
the RAM inside your phone so if a RAM manufacturer is trying to increase

22
00:01:40,479 --> 00:01:44,640
supply to serve a bunch of different use

23
00:01:43,680 --> 00:01:49,360
cases all they really have to do is shrink the

24
00:01:46,880 --> 00:01:54,479
process node so they can fit more RAM chips on one wafer then they cut it up

25
00:01:52,479 --> 00:01:58,079
like a square cut pizza and send however many chips to buyers serving each of

26
00:01:56,320 --> 00:02:02,479
these different segments contrast that with something like

27
00:01:59,840 --> 00:02:07,840
manufacturing displays where different resolutions and panel types mean that

28
00:02:05,200 --> 00:02:12,160
serving many different markets is much more challenging for any single

29
00:02:09,840 --> 00:02:18,160
consolidated manufacturer so this ends up meaning that more external forces are

30
00:02:15,360 --> 00:02:23,200
exerting influence on how much dram and nand will cost you and also means that

31
00:02:20,879 --> 00:02:28,160
manufacturers have a much harder time estimating how much supply they need to

32
00:02:25,360 --> 00:02:33,440
keep on hand that means that both supply gluts and shortages are more likely

33
00:02:31,120 --> 00:02:37,920
shortages can and have been caused by many different things for example there

34
00:02:35,519 --> 00:02:42,720
can be unforeseen high demand when a hot new phone comes out that everyone wants

35
00:02:40,319 --> 00:02:47,920
or even a service that causes a spike in demand on the server side of things i

36
00:02:45,599 --> 00:02:52,000
mean think how much more memory google might suddenly require if their stadia

37
00:02:49,920 --> 00:02:56,160
game streaming service were to take off good luck with that other times supply

38
00:02:54,239 --> 00:03:00,160
can be strained by production problems such as power outages that disable the

39
00:02:58,239 --> 00:03:04,159
systems used to maintain their dust free environments on the production line

40
00:03:01,920 --> 00:03:08,319
meaning that manufacturers have to scrap whatever's on the line and start from

41
00:03:06,159 --> 00:03:13,360
scratch now this might only set things back a week or two and have a minimal

42
00:03:10,640 --> 00:03:18,400
impact on prices but other times natural disasters like earthquakes and fires

43
00:03:15,760 --> 00:03:22,239
have shut down fabs for months at a time resulting in significant shortages in

44
00:03:20,319 --> 00:03:27,599
supply something that notably happened to sk hynix back in 2013. there's also

45
00:03:25,360 --> 00:03:31,360
the possibility of politics muddying things up as they so often do for

46
00:03:29,920 --> 00:03:36,640
example there was a trade dispute between japan and korea in 2019

47
00:03:34,480 --> 00:03:41,360
japan supplies lots of raw materials used in the manufacture of dram and nand

48
00:03:39,040 --> 00:03:44,720
meaning that the fabs in korea couldn't get the ingredients they needed for a

49
00:03:43,519 --> 00:03:50,159
short while now that situation was fortunately resolved quickly but any kind of more

50
00:03:48,480 --> 00:03:54,799
protracted conflict could have driven prices up in a big way of course

51
00:03:52,799 --> 00:03:59,840
sometimes mishaps end up working in the consumer's favor instead in the mid

52
00:03:57,200 --> 00:04:04,159
2000s there was a huge surge of people buying mobile devices like phones and

53
00:04:02,080 --> 00:04:07,599
the RAM manufacturers assumed that this trend would just

54
00:04:05,360 --> 00:04:12,560
keep going the way that it was so they started churning out lots more RAM but

55
00:04:10,159 --> 00:04:16,720
instead the market got saturated suddenly everybody already had a phone

56
00:04:15,680 --> 00:04:20,560
or two and sales slowed down so suddenly there

57
00:04:18,720 --> 00:04:24,240
was a lot of excess supply meaning that folks who bought RAM during this time

58
00:04:22,400 --> 00:04:28,400
ended up getting a bargain there have even been times that memory prices have

59
00:04:25,919 --> 00:04:32,720
been pushed below the manufacturing cost for the dram chips because it's worse

60
00:04:30,720 --> 00:04:37,040
for the manufacturers to shut down the fabs than to keep pumping out chips at a

61
00:04:35,360 --> 00:04:41,680
loss like during the great pringles incident of 1994

62
00:04:39,360 --> 00:04:45,280
which actually wasn't a real thing it was never a pringles incident

63
00:04:43,919 --> 00:04:49,680
