Advantages of DRAM | disadvantages of DRAM
This page covers advantages and disadvantages of DRAM. It mentions DRAM advantages or benefits and DRAM disadvantages or drawbacks. DRAM stands for Dynamic Random Access Memory.
What is DRAM?
• It uses capacitors to store the information.
• Charge and discharge of capacitor is carried out to change the stored value.
• It uses trasistor as "switch" to store charge or to charge/discharge.
• Periodic refresh of charge is required as charge leaks off.
There are different types of DRAM viz. SDRAM, DDR DRAM, RDRAM etc. Refer SRAM vs DRAM vs MRAM >>.
Benefits or advantages of DRAM
Following are the benefits or advantages of DRAM:
➨DRAM memory can be deleted and refreshed while running the program.
➨Cheaper compare to SRAM.
➨It is smaller in size.
➨It has higher storage capacity. Hence it is used to create larger RAM space system.
➨It is simple in structure than SRAM.
Drawbacks or disadvantages of DRAM
Following are the disadvantages of DRAM:
➨It is comparatively slower than SRAM. Hence it takes more time for accessing data or information.
➨It loses data when power is OFF.
➨It has higher power consumption compare to SRAM.
