Samsung has started the manufacturing of the industry's first 16GB LPDDR5 DRAM for Mobiles. It has a data transfer rate of 6,400 megabits/second(Mbps), which is 16% faster than the present 12GB DDR5 DRAM that has a data transfer speed of 5,500 (megabits/second). 12GB DDR5 DRAM is presently used only in high-end devices like ASUS ROG 3, Lenovo Legion 2 gaming smartphones and we have experienced a tremendous data transfer speed and performance in those devices.

The 5G Smartphones are arriving in the market and within a few months, we can enjoy the full benefits of 5G and can experience excellent data transfer speed with 16GB DDR5 RAM.
Samsung claims that this chip has a data transfer speed of more than 50GB per second which means we will be able to transfer 20 Full HD+ movies in just a second. Samsung also claimed that DDR5 RAM is compatible with any smartphone with the latest technology and Samsung will start manufacturing and supplying it to other Smartphone manufacturers.

What is RAM and what is the difference between RAM and ROM?
RAM(Random Access Memory) is the internal memory of the CPU for storing data. It can read/write the data only when the power is ON and will lose the entire data when the power goes OFF. RAM stores the memory of the APP or Software until we are running it and will release the memory after closing the APPS or Software.
RAM is of two types SRAM and DRAM:

ROM is the internal storage of the device. Read-only memory (ROM) is a type of non-volatile memory used in computers and other electronic devices. Data stored in ROM cannot be modified after the manufacture of the memory device.
