It says it can be programmed electrically, but can only be erased by UV light. Does that mean that once the chip has been programmed, you are unable to overwrite the settings with electrical signals? Does the chip need to be erased via UV light to change any programming? |

Is the table in this article up to date? I can't believe the largest EPROM is only 512kb. sjorford →•← 10:02, 21 Mar 2005 (UTC)
The table isn't really inclusive. It only lists one family of devices. There are larger ones, but I've never heard of one > 20 megs. Certainly, the common ones are all pretty small. - Bryce
The first EPROM was the 1702 (256x8 = 2k memory) used to store the firmware or boostrap of the first microcomputers or programmable calculators.
