Difference Between SRAM and DRAM

Main Difference

DRAM is a type of Random-access memory that stores everything from within data using separate capacitor within an incorporated circuit. Dram is a unit found inside a CPU of your computer. Sram is a form of computer data storage and it uses more transistors per bit of memory than Dram. Scram works for cache memory of a computer but Dram works with main memory. Sram is static and a bit faster but Dram is dynamic and bit slower than the former. Sram uses less energy than Dram does. As everything is more in Sram, it is also expensive than Dram. Dram needs to get refreshed following read functioning. Refreshing isn’t needed for Sram. Dram is taken as main memory in a computer and is not for long-term storage. Sram is used for L2 and L3 cache in a CPU. Sizes of Dram may range from 1GB to up to 16GB. Sram may only size ranging from 1MB to 16MB.

Definition of DRAM

DRMA, an acronym for Dynamic Random-Access Memory, is a type of random-access memory works to accumulate each bit of information or date in a split and separate capacitor within an integrated circuit. Dram is a type of main memory of computer, and is commonly used for CPU caches. Its structure is simple as only one transistor and a capacitor are needed per bit. This simplicity helps Dram to approach very lofty densities. It is volatile memory as it loses its data very quickly soon after removal of power supply. Extremely tiny transistors and capacitors are used in Dram and billions can be placed on a single memory card. It consumes much more power with several ways of managing this consumption and usage of energy. Dram is usually installed in a rectangular range of charge storage cells consisting of one capacitor and transistor per data bit. Dram stores each bit of data as a negative or positive electrical charge in a capacitive make-up. Memory size in Dram starts from GBs.

Definition of SRAM

SRAM, an acronym for Static Random-Access Memory, is a sort of data storage in the CPU. It caches data bits in its memory until the power-supply continues. Sram doesn’t need to get refreshed. Modules in Sram are much more simpler, and this distinction makes it easier for most users to devise an interface to access the memory. Number of transistors needed to store memory is much higher in Sram. Where need of speed is paramount, Sram is prioritised. It uses less power and functions much faster but it is an expensive tool.

Differences in a Nutshell

1. Sram is static; Dram is dynamic
2. Less power is needed in for Sram; Dram consumes more power
3. Sram works faster than Dram
4. Number of transistors used in Sram is higher than those used in Dram
5. Sram is usually used in cache memory; Dram is used in main stream memory
6. Sram is expensive; Dram is available at cheap price
7. Dram may size in GBs; Sram only comes in MBs
8. Sram works for L2 and L3 cache in a CPU; Dram is not for long-term storage
9. Refreshing is need in Dram; Sram doesn’t need refreshing
