The contents of SRAMs get erased when power is switched off.Thus it is called a volatile memory.

The two largest selling types of memory integrated circuits are DRAMs and SRAMs.
Usually memory banks made up of SRAMs or DRAMs or EPROMs consist of the storage area provided on a microprocessor. For understanding how the address space of a 20 bit address line microprocessor is organised, read about address decoding for even and odd memory addressing through SRAMs and EPROMs.
RAM is a volatile Memory. But ROM is not volatile.
