TYPES OF RAM(RANDOM ACCESS MEMORY)

The types of  (RANDOM ACCESS MEMORY) are given below in detail's:-


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 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 processing. 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.

MRAM stands for Magneto resistive Random Access Memory. It stores data using magnetic charges instead of electrical charges. MRAM uses far less power than other RAM technologies so it is ideal for portable devices. It also has greater storage capacity. It has faster access time than RAM. It retains its contents when the power is removed from computer.
