SRAM vs DRAM

SRAM is used in the CPU as Cahce memory as it is incredibly fast

Static RAM (SRAM)

• SRAM uses on-chip memory to store data, which makes it very fast.
• It is used in the CPU Cache memory because of its speed.
• It costs more compared to DRAM
• It has a lower storage density (amount stored per area)

DRAM is used in main memory due to it’s cheaper cost and higher storage density than SRAM

Dynamic Ram (DRAM)

• DRAM uses off-chip memory to store data,  which means it is fast, but not as fast as SRAM
• It is used in the main memory
• It costs less compared to SRAM
  • It has a higher storage density compared to SRAM
