Semiconductor memories are of two kinds: Random access memory (RAM) and ROM (read only memory).
RAM: a read/write memory.Information can be there written in and read from a RAM. This is volatile memory.This stores information as long as power supply is on.
ROM is permanent kind memory. Contents of this are not lost while power supply goes off. There user cannot write in a ROM. Contents of this are decided by the manufacturer and also written at the time of manufacture. There programmable ROMs are also available. They are termed as PROMs.
