Dynamic Random Access Memory contents need to be continuously refreshed. When its contents are being refreshed, memory can not be read from nor write to. Another point to note is that DRAM is cheap to manufacture (This could be the only advantage it has to SRAM).Where as in Static Random Access Memory, memory need not to be continuosly refreshed and therefore memory can be accessed at any time. SRAM is expensive to manufacture.
DRAM has a lower price. Further details below:

DRAM and SRAM
SRAM is less dense than DRAM because SRAM cells are made up of multiple transistors, typically 6 transistors per cell, which require more space compared to the single transistor used in DRAM cells. This extra space needed for each cell in SRAM makes it less dense in terms of storing data compared to DRAM.
Static Random Access Memory (SRAM) entries are constant and fixed, the information stored in this type of memory does not degrade over time. Dynamic Random Access Memory (DRAM) slowly leaks over time and must be refreshed from time to time.
SRAM DRAM SDRAM XRAM is not a form of RAM.
Static RAM and dynamic RAM are two available types of computer RAM, or Random Access Memory. One advantage of static RAM is speed, while a disadvantage is cost. An advantage of dynamic RAM is storage space, while a disadvantage would be speed.

DDR and DDR2
•Dynamic cell (DRAM) -Simpler to build, smaller -More dense -Less expensive -Needs refresh -Larger memory units •Static (SRAM) -Faster -Cache
---SRAM--- Static random access memory (SRAM) is a type of semiconductor memory where the word static indicates that it, unlike dynamic RAM (DRAM), does not need to be periodically refreshed, as SRAM uses bistable latching circuitry to store each bit. SRAM exhibits data remanence, but is still volatile in the conventional sense that data is eventually lost when the memory is not powered. The term SDRAM, which stands for synchronous DRAM, should not be confused with SRAM.
