Hi,

What is the difference between flash memory and eeprom?

As far as I know, with EEPROM you can erase/reprogramme individual bytes.
You can only erase/reprogramme Flash in banks of many bytes. Use google
for more details.


Which one is more reliable?

No idea - look at some datasheets.

cheers,

Thanks!



Also, if what I've been using is typical, flash has a write-life. That
is, after so many erase/write cycles (50,000) it may begin to fail.

John

Both flash and EEPROM have write lives (in cycles) and data retention
lives (in years). The basic cell AFAIK is the same, so for recent
technology devices they will have comparable lives. The difference is
that the flash part saves a lot of real estate with it's block erase, so
in general if the chip has a lot of memory it'll be flash and if it has
only a little it'll be EEPROM.

In fact, for "big" chunks of memory I don't know of anything _but_ flash
being currently available, and the little 256-byte 8-pin parts are all
EEPROM for convenience in parameter storage. There are older EEPROM
chips, but that's only because EEPROM came along several years before
flash did.

Thanks, Tim. I didn't know that.

I once peer-reviewed a design which periodically "refreshed" a couple of
EEPROM locations. Turns out the idea used up the entire life of the chip
in about 3 weeks. oops. They re-designed the firmware, scrapping the
not-so-brilliant idea.

AFAIK the failure method is increased write cycle time.

You're looking at morality and ethics in a very
simplistic way. "Doing good" may involve allowing others to feel small
pain in order that they may learn to avoid great pain.

Frinst, a teacher first strikes a student with the flat
of the sword. The student either learns to parry, or to quit screwing
around with swords.



You're missing one major fundamental difference here:

This particular student signed up, voluntarily, to be slapped by the
instructor.

Inflicting pain against the will of your victim makes you no better
than a common murderer.

Here is a poem by Calvin Trillin (of "The Nation") which he published

McCain

So now comes forward John McCain--
A high-tech version of Gawain
When with his steed, a Navy plane.
He says he's forming his campaign
Committee, which will ascertain
If someone known for speaking plain
And taking stands that are the bane
Of those protecting their domain
With campaign cash that they obtain
From fat cats who might then ordain
In laws some clauses that pertain
To only those whose favors gain
The sort of access that's germaine
Can, in a party whose disdain
For folks who go against the grain
Has caused reformers only pain,
Be nominated to regain
The White House for a for-year reign.
Or, as the experts all maintain,
Does John McCain campaign in vain?
