When was DDR4 ram released?

Have you ever wondered about the historical background of computer RAM?

You may have heard of some types of RAM, such as DDR4, DDR5, and even the new Z-RAM. But do you know the history of this kind of memory? And you can answer questions like who was the inventor of RAM. Or when DDR4 RAM came out?

RAM or main memory was implemented as a buffer due to the increasing speed of microprocessors and the slowness of secondary memory (mass storage media such as hard drives). In this way, software processes (data and instructions) can be loaded and accessed faster by the CPU.

The first RAM memory was invented by John von Neumann in 1947. He called it “the carousel”; He later also called it “random access memory”.

It would take another 2 years for RAM to become mainstream. In 1966, Robert H. Dennard of IBM developed DRAM (dynamic random access memory) of a transistor. His invention made RAM faster and cheaper to manufacture and ushered in a new era of computing.

The history of RAM begins between 1949 and 1952, when some of the first types of magnetic core RAM began to be developed and used.

When was DDR4 RAM released?

DDR4 SDRAM was introduced in the second quarter of 2014, focusing on ECC memory, while non-ECC DDR4 modules accompanied the launch of Haswell-E processors requiring DDR4 memory in the third quarter of 2014.

Early Haswell-E CPU models require a BIOS update to work with DDR4 memory, and so far, only Intel’s own motherboard vendors have made the corresponding changes to their CPUs’ microcode (as of early September 2014), leaving most third-party motherboards at best. making it incompatible with Haswell-E from the beginning.
