RAM and Types

What is RAM?

RAM is the memory of a computer that can be read and changed at any time. The information stored in this type of Memory is lost when the power supply to the PC or laptop is switched off. It is known as the main Memory or temporary Memory or cache Memory or volatile Memory of the computer system. The full form of RAM is Random Access Memory.

What is DDR3?

DDR3 is an essential type of 3rd generation SDRAM utilized for system memory. This type of RAM is capable of transferring data from one location to another at a higher speed. The full form of DDR3 RAM is Double Data Rate.

What is DDR4?

DDR4 RAM is the latest variant of RAM, which is used widely in the next generation of computing. Courtesy of the decreased voltage and increased transfer rates of DDR4 can offer optimum efficiency and higher speed. The full form of DDR4 SDRAM is Double Data Rate Fourth Generation Synchronous Dynamic Random-Access Memory.

DDR3

DDR3 RAM stands for Double Data Rate version 3.

DDR3 RAM was introduced in 2007.

The cost of DDR3 is lesser than DDR4.

DDR3 consumes less power than DDR2 but more than DDR4.

The speed of DDR3 is slow in comparison to DDR4.

DDR3 maximum memory size is 16 GB.

The clock speed of DDR3 varies from 400 MHz to 1066 MHz.

DDR3 has lower latency than DDR4.

DDR3 has lower latency DDR4 has more latency than DDR3

Auto-refresh and self-refresh are performed for content.

DDR3 RAM includes ECC memory, which compresses extra data byte lanes.

DDR3 RAM works on 1.50 V voltage

DDR3 RAM has a 240-pin interface.

This type of DDR RAM is backward compatible with the older RAM generations.

Decade-old demand for DDR3 RAM is waning.

DDR4

DDR4 RAM stands for Double Data Rate version 4.

DDR4 was reading released in 2014.

DDR4 cost is higher or more than DDR3.

DDR4 consumes less power than DDR3.

DDR4 speed is faster than DDR3.

DDR4 has no maximum limit or capability.

The clock speed of DDR4 varied from 1066 to 2133 MHz.

DDR4 has more latency than DDR3.

Only self-refresh is performed for a content.

DDR4 RAM offers computing capabilities on different platforms like smartphones, tablets, PC, laptops, etc.

DDR4 RAM works on 1.20 V voltage.

DDR4 RAM has a 288-pin interface.

This type of DDR RAM is not backward compatible with the older generation’s RAM.

The demand for DDR4 RAM is on a constant rise because of its implementation of emerging technologies.
