EPROM Memory chips

[Windstar]

I have 2 PC100 Eprom 64 mb memory chips. when I put them in my machine it only sees 1 chip.
Are there issues with this type of memory that will not allow for multiple Chips in the machine? Also what does the Eprom do?

I don't know what the EPROM on memory does. But I know what an EPROM is;

erasable programmable read-only memory
