I often see Coin size batteries on circuit boards
What kinds of IC chips are these coin size batteries for?
I have seen coin size batteries 3vdc for NVRAM, but what is on NVRAM chips mostly? the settings or bios?
The coin size batteries get low in voltage and often need to be replaced. Once you replace it with a new batteries don't you have to load or burn the code back into the NVRAM chip?
