Since the RAM introduction in DIMM format, various memories have been available in the market. However, DDR RAM has prevailed above all these since 2000. Most desktops, tablets, and laptops have been using RAM to store data for short-term data required to function properly. With the evolution of computing systems over time, RAM has also improved.

Throughout these years, various types of RAMs have entered the market ranging from DDR to DDR4. In this article, we will learn about these different RAM types.

So, here we go:

Different types of RAMs you need to know.

Here are the most common RAM types you must know:

DDR

DDR is a RAM type introduced in the 2000s. This RAM type transfers data to the processor on clock signals upbeat and downbeat. It will transfer data at a double rate. The use of upbeat and downbeat for data transfer makes DDR a faster RAM type that can transfer data one clock signal edge only.

This RAM type typically transfers data between 266 and 400MT/s. However, you must remember that double data rate and dual channel memory are different.

Over time, DDR RAM technology has also experienced various improvements that enhanced the overall performance of computers.

DDR2

The second DDR generation that superseded the original DDR RAM is DDR2. Besides double pumping the data transfer speed, DDR2 RAM has also improved data bus speed with reduced power. The DDR2 RAM achieved this with an internal clock running at half the data bus speed. Combining all these factors produces four total data transfers for every clock cycle.

Due to this, DDR2 can provide the same bandwidth as DDR RAM but with higher latency.

DDR3

DDR3 is a dynamic RAM type that was introduced in 2007. It is a popular type of RAM for its higher bandwidth than others enlisted in the article.

This RAM type isn't forward or backward-compatible with any earlier RAM type. It is mainly because DDR3 differs regarding signaling voltages, timings, etc.

The key capability of the DDR3 RAM type is that it can transfer data at eight times the internal memory arrays' speed. It ultimately enables higher peak data rates and bandwidth. The power consumption of this RAM type varies as per multiple factors. These include:

  • Voltage
  • Speed
  • Usage type, and more.

DDR4

DDR4 came to the market about 7 years after DDR3. It features a lower operating voltage with the highest data transfer rate than all other DDR generations previously. The RAM type can process four data rates for a cycle.

  • DDR4 takes less power and is more efficient and faster than the previous DDR RAM generations.
  • DDR4 can process various data requests in one clock cycle.
