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	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
