The Flash Destroyer, our new EEPROM tester, is going to reach the first million write cycles in the next few hours (see a live stream here). Can you guess what the final write count will be when the EEPROM dies? We’ll give a couple unpublished Dangerous Prototypes PCBs to the three closest guesses.
You can preorder the Flash Destroyer ‘I like to solder’ kit for $30, including worldwide shipping.
hmmm, what about… 1234567 wryte cycles?
4815162
(4 8 15 16 23 42)
Can it count past 10M-1?
ill guess 1.65 million.
ill guess 8.7 million.
The way it writes bits, i would guess 2 550 000 :)
1.5 million, I dont think it will pass the 2 million at all…
I’ll guess 1 million.
my guess 1,570,796 cycles
(pi/2*1000000 :)
My guess is 3,149,462
1,270,985
I guess maybe 01189998819991197253 cycles…
But seriously 1.8 million of cycles…
42 times since it is the answer to life, the universe, and everything
but I’d say 1.74 millionish
Guys, you guess too low :) I’ll stay with my 10M cycles as I said in the first post
I second that, the temperature’s just not high enough. My guess: 9 999 999 cycles!
My guess is for 3.5 million cycles :)
1.337.111 +/- 10% ;)
12M
5,000,000
8.888.888 is my guess…
11,500,000
1.4 Million!
1.37 million
2 015 640
Actually I think I want to change that to about 13 million, the temperature is really low so will extend the amount of cycles.
That is hysterical. Try this with field programmable gate arrays and see if they emerge into some proto-consciousness and discover you are planning and testing for their own demise. 1.78 millioin
I guess 1,108,579
will it roll over and keep going or stop at 9999999?
It will keep going. The internal counter is 32bits, so it can count a lot higher than that, but the display will only show the LSB. I’m working on an update now in anticipation of reaching 10M – it will show the MSB and use the decimal points to shows the number of missing 0s.
Can’t you just add more digits? Larger number looks cooler :)
I guess that… is there a bug in the project! Perhaps detecting the error condition. My boards, please :-)
1,987,654 :)
While you’ll wait another week to see the first error I suggest reading these appnotes:
http://ww1.microchip.com/downloads/en/AppNotes/01019A.pdf

Great read! There is a table on page 3 of 01018A that shows life at temperature. This is a good quote:
[quote]
The higher the temperature, the worse the
endurance will be. Generally, and approximately, a
device which fails at 10 million cycles at 25°C will fail at
2 million cycles at 85°C and 1 million cycles at 125°C.
The reasons for this are not conclusive (although there
is much technical literature supporting one theory or
another), but it is apparent that the failure mode of
EEPROM cells (electron trapping in the tunnel
dielectric causing shielding and dielectric breakdown)
is strongly dependent on temperature.[/quote]
I think 9 million cycles
2 900 000 :)
1.3e6
I mean 13e6 (13 million)
2,113,045
7,777,777 :D :D :D
12 121 212 Cycles (12.1 M )
2,997,890
*Hope I Win*
~15.000.000
4.567.890 i think
I think 1.900.009
My guess is about 25000000 (25 million)
4, 444, 444
9,999,999
3,600,000
31337801
5 900 000
let’s say 16 000 000 writes.
Well if I have to guess I would guess 9 469 043, Now I am curious to see how close (or not) I got.
I’d say 20,000,000 read/writes.
I have read somewhere that tests like this one might show much higher cycle counts than would in normal use condition, as the power is not recycled between read/writes. so I wouldn’t be surprised if the cycles produced in this experiment is many folds higher.
Ok my Guess – 15,555555
4,885,932
gogo
17321123
My guess is 11.7M cycles.
2,500,000
13.8M
3,487,110 :-)
54,967,295 -> a random radioactive particle will cause an error… even better I think it will be an Alpha particle for some reason.
9,786,421
5,480,342… (+/- 10,000,000) :)
7,360,000
9,876,543
/Assuming that it’s not set to roll over once it hits 10 mil.
3,854,722 :-)
11,527,253
possibly never or when it is powered off between checks
4,871,302 ;0))
My guess is 14,555,191
My guess is 7,654,321
6,627,012 :-)
8,847,114
My guess is 9,874,312
12,856,478
You could use hexadecimal (or by more symbols, some other system) AFTER it has passed the 9999999 limit? Or use the dots as you said before, but in binary form :) 2^7 zeroes = much :)
9,999,999 if it can’t roll over.
16,150,000 if it can.
It will show decimal points and drop the least significant digits.

“everything dies, but that’s OK”….
23.456.789 cycles?
13,457,882
The final count is 11.49million cycles. The destruction started at 8:11 UTC on May 25, and it took almost exactly 13days to reach the first error. The final count and closest guesses are here:

Thanks for participating.
Hey Ian , please run it again ,this is more fun than the eurolotto !
