Good move.

The real key here, as both Sman and dy2147 are currently pointing out, is in the Flashback diagram.

Some sort of onboard ROM or RAM is permissable, even essential, but these are no good for storage. ROM is by definition "Read Only Memory" and therefore can't be written to and can't store any incoming data. RAM is Random Access Memory. It can be written to, BUT it is volatile, meaning all data is lost when the device powers down. Thus neither ROM nor RAM can serve as memory for the received processed sound. Flash memory is non-volatile, meaning it retains the data when power is removed.

So, if the device, has no onboard/non-removable storage for the received processed sound and relies entirely on removable flash memory to store this sound, then the device falls under the terms of the patent, regardless of whether it has ROM or RAM. If the device has onboard/non-removable, non-volatile memory which is used to store the received processed sound, it isn't covered.

Keep showing that diagram whenever and wherever possible.

Capiche?
