What is DRAM?

What is DRAM?
Dynamic RAM refers to volatile RAM that is constantly refreshed to prevent stored contents from being lost. All modern RAM is of this type, though there have been improvements. Data is stored in the form of rows and columns, with each storage area in RAM having a unique address that is a combination of the row and column number. DRAM was available in different types like SDRAM, EDO (Extended Data Out) RAM, FP (Fast Paging) RAM, and more, all of which are now obsolete except for SDRAM.
