Q

Features of flash memory?

A
  • Can be re-written
  • Usually fast to access
  • they don’t have any moving parts
  • Usually high capacity
  • Robust (not effected by vibrations so can be used in industrial machines)
  • Short life time- can only be written a certain number of times before data is lost. We may lose connection once the flash has degraded past a point. Re-writable devices include several blocks of flash memory so they last longer.
