Diffrence Between DRAM or SRAM

DRAM (Dynamic random access memory)


  • it needs to be refreshed in every few milliseconds.
  • it stores data either capacitor charged or discharged.
  • e.g - 2GB RAM of pc/laptop.

SRAM(Static random access memory)

  • SRAM doesn't need to be refreshed periodically.
  • it stores data as long as power is being supplied.
  • e.g - cache memory in CPU.

DRAM vs SRAM

Dynamic random-access memory (DRAM) Dynamic random-access memory (DRAM) is a type of random-access memory that stores each bit of data in a s eparate capacitor within an integrated circuit. The capacitor can be either charged or discharged; these two states are taken to represent the two values of a bit, conventionally called 0 and 1. DRAM is the memory we use as physical memory that helps the PC/laptop to run applications. A DRAM storage cell is dynamic in that it needs to be refreshed or given new electronic charges every few milliseconds to compensate for charge leaks from the capacitor. example  PC/laptop it has 2GB of RAM. Static random-access memory  (SRAM) SRAM (static RAM) is random access memory (RAM) that retains data bits in its memory as long as power is being supplied . SRAM does not have to be periodically refreshed . example of SRAM is SRAM is used as cache memory.
