Difference between SRAM and DRAM

Difference between SRAM and DRAM

In this tutorial, we are going to study about the difference between SRAM and DRAM.


RAM or random-access memory is used to store the programs and data that are modifiable. Ram chips are available in two forms:

  1. SRAM or static RAM
  2. DRAM or dynamic RAM

Given below is the major difference between SRAM and DRAM:



SRAM has lower access time

DRAM has higher access time

Due to lower access time, SRAM is faster

Due to higher access time, DRAM is slower

SRAM requires constant power supply thus it consumes more power

DRAM consumes less power as it stores information in the capacitor.

SRAM has lower low packaging density

DRAM has higher packaging density

SRAM is costlier than DRAM

DRAM is cheaper than SRAM
