Flash memory is nonvolatile (it does not need a trickle of power to maintain state). If it were, SD/uSD/SSD/NVME memory would be wiped the second they were disconnected from a device and every device would lose its firmware when it lost power.
- rablackburn 5y agoHuh, why does the device “have to be left switched on” for then? If it’s non-volatile it doesn’t matter right? Or is the point that the counter only counts time when the device is on? Kinda of like anacron vs cron
- Beldin 5y agoThe latter. Counter is stored persistently; power is needed only to decrease the counter (according to the article).
