What is significance of ras and cas in SDRAM?

SDRAM receives its address command in two address words.It uses a multiplex scheme to save input pins. The first address word is latched into the DRAM chip with the row address strobe (RAS).Following the RAS command is the column address strobe (CAS) for latching the second address word.Shortly after the RAS and CAS strobes, the stored data is valid for reading.
