There are three main types.

DRAM - Dynamic Ram, which is the RAM in most computers. It's called Dynamic because there is a need for circuitry in the computer to constantly refresh the data. It will lose all data if power is removed.

SRAM - Static Ram. Not as common but used to be used in laptops and portable devices. Called Static as you don't have to refresh all the time, but it does lose the data if you turn the power off. It is lower power than DRAM, but not as high capacity

Flash RAM - though there are lots of names for this. Used in USB keys etc. It saves data even after the power is turned off. Access to it is a lot slower than DRAM.
