DRAM
▪︎DRAM stands for Dynamic Random Access Memory.
▪︎It is used in most of the computers.
▪︎It is the least expensive kind of RAM.
▪︎It requires an electric current to maintain its electrical state.
▪︎The electrical charge of DRAM decreases with time that may result in loss of DATA.
▪︎DRAM is recharged or refreshed again and again to maintain its data.
▪︎The processor cannot access the data of DRAM when it is being refreshed.
▪︎That is why it is slow
SRAM
▪︎SRAM stands for Static Random access Memory.
▪︎It can store data without any need of frequent recharging
▪︎CPU does not need to wait to access data from SRAM during recharging
▪︎That is why it is faster than DRAM
▪︎It utilizes less power than DRAM
▪︎SRAM is more expensive as compared to DRAM
▪︎It is normally used to build a very fast memory known as cache memory.
