Saving to Flash

Is there a difference between the results of the commands "copy run flash"  or "write mem" ?

Copy run flash will write the running config to the flash memory.

Write memory will put the running config in the nvram.

When the device boots up it will search for the running config in nvram, based on the configuration-register value that you have set.

The former is the newer and recommended command, the latter is the older and, desired to be, deprecated command.  (The latter is likely still available because it's probably still very commonly used and popular.)
