Why are flash memory chips popular in pocket-sized devices?
And how can they fail? what strategies are put in place to minimise these effects?
Answer:
Sometimes it's easier to transfer music and video directly to the flash card than it is to use the pocket devices application interface.
It's usually faster, too. Because you can put a huge amount of data on a very small card, and there are no moving parts so they're great if you're going to be moving around. I believe the only way they can fail is if they come close to a strong magnetic field, but I may be wrong on that. It'll be appearant when you consider when and where those devices are used:
battery: flash has no moving parts needs less power, wins over microdrives.
on the road: no moving parts means no mechanical failure, wins over MD.
performance and size: PDAs don't need to scale up like MDs can for the performance and size (physical and capacity) so MD looses.
Flashes are EEPROM technology, guess the failure point of Electronically Erasable Programmable ROM, there are controller chips inside each flash card to avoid accidental electric contacts going into the actual Flash part. No moving parts. No failures if there are no moving parts. flash memory is the memory which has a temporary memory in it other than any hard-drive. so u can store songs and other files at a very high speed. They're popular because you can get a large amount of data in a small amount of space.
