What is Dynamic Random Access Memory and Static Random Access Memory?
Dynamic Random Access Memory (DRAM);
DRAM stands for Dynamic Random Access Memory. This type of RAM is used in most
of the computers. In order to maintain data in DRAM, it is refreshed with
electric charge again and again; otherwise data stored into it can be lost. It
utilizes more power. During refreshing process, CPU cannot write and read data
to and from the DRAM. That is why-it is slow.
Static Random Access Memory (SRAM):
SRAM stands for Static Random Access Memory. It does not have to be refreshed with electric charge again and again. It is faster than DRAM because CPU does not have to wait to access data from SRAM. SRAM chips utilize less power. However, SRAM is more expensive than the DRAM.
Difference Between DRAM and SRAM:
DRAM has to be refreshed with electric charge again and again. SRAM does not
have to be refreshed with electric charge again and again. DRAM utilizes more
power, while SRAM utilities less power. DRAM is slower because CPU does not have
to wait to access data from it. SRAM is faster than DRAM because CPU does not
have to wait to access data from it,
