Difference of DRAM from SRAM



DRAM or Dynamic Random Access Memory is the main memory and needs constant refreshing making it slower while SRAM or Static Access Random Memory is the cache memory that does not need refreshing but it is thus more expensive.

DRAM is physically stored on Dual Inline Memory Module (DIMMs) having a 64 bit path that uses EDO or Extended Data Output and (Single Inline Memory Module) SIMMs with a data path of 32 bits and comes in a variety of ways such as PFM or the Fast Page Mode while SRAM is housed on the system board on Cash on a Stick (COAST) modules or single chips or included inside the processor case.

Computer RAM Memory and Its Significance

Computer RAM or random-access memory is one kind of computer memory that can be used indiscriminately. It acts as the main memory of the computer system. It allows accessing any byte without the interference to its prior bytes. It is mostly the common type of memory used in computer systems and sometimes in printers. Generally, two types of RAM are available, namely- DRAM or Dynamic random-access memory, and the other is SRAM or Static random-access memory.

DRAM is widely used because of its availability and cheap cost, while SRAM is relatively expensive but faster than DRAM. For DRAM, it is necessary to refresh the system continuously whereas, SRAM doesn’t require any refreshing. Moreover, the data transfer rate is faster in SRAM rather than DRAM. However, you should pick your desired RAM according to your budget.
