Static RAM has lower density because there are total 6 Transistors(Occupying More Space) while DRAM has one transistor and capacitor.
Therefore the Density (SRAM) < Density of (DRAM).
Power Consumption:
As DRAM has a capacitor it, continuously leaks current. Therefore it requires frequent refresh which consumes power.
Therefore Power Consumption(DRAM)> Power Consumption(SRAM)
