BIOS is a program (stored in ROM), not a memory.
However the BIOS uses a battery backed up RAM to store a variety of settings and parameters. This BIOS RAM is itself volatile (it can only store data when powered), however the battery backup provides power to this RAM when the main power of the computer is off (making it act as if it were nonvolatile). When this battery dies the BIOS RAM will lose its data and (after the battery is replaced) the machine may have to be reconfigured from scratch before the machine will startup correctly.
The BIOS is stored in non-volatile memory. The BIOS software is built into the PC, and it is the first software run by a PC when powered on.
Bios stand for
Non-volatile
ROM is non-volatile memory.
Uranium is a non-volatile solid metal.
BIOS is a set of boot programs stored on a non-volatile ROM on the motherboard which is different for every system configuration. That would simply mean that unlike other programs it has direct hardware control.

DRAM is volatile.

Volatile is RAM and non-volatile is like a hard drive. More specifically, "Volatile" storage will erase its contents when power is removed, while "Non-volatile" storage will have permanently stored the data (until specifically told to erase it), even after power is removed.
