RAM Advancements - From SDR to DDR4 and More

Since the development of various PCs in modern smartphones, storage standards have always been a determining factor in the performance of the overall system. Over time, it has constant SDR updates or single-data-rate RAM on older computers of the bygone era, up to the recent DDR or the Double Data Rate.

From day one, one of the important factors influencing the performance of a device was the inability of the memory to adapt to processor speeds. The introduction of double data performance was revolutionary in that it demonstrated the performance of the memory bus as a function of processor speeds. This resulted in an optimal performance of the system.

The transition to SRAM and DDR has been constantly updated to quickly respond to the demand for innovative innovation. Starting with the 200 MHz SRAM in early 2001 on the 400 MHz DDR2 in 2002, this was just the beginning of an impressive journey. At the end of 2007, DDR2 was able to respond to memory rates of up to 1066 MHz, and 2009 was even better with the introduction of DDR3.

Today, the latest generation of the DDR4 series has conquered the market with even better performance and robust control features. In addition to performance and speed, it offers improved power savings for an enterprise, tablet, microserver and ultra-thin client applications.

This new solution has many advantages over its predecessors. This is one of the main reasons why most applications implement the previous DDR4 upgrade. It comes with a bitrate from 2 GB to 16 GB, which allows high-capacity subsystems. Compared to a maximum of 16 GB per DDR3 DIMM, the DDR4 standard allows DIMMs up to 64 GB.

There are many types of DDR4 connectors and modules in the market. Ultra Low Profile Vertical (ULP) DIMM sockets provide an ideal solution for ultra-thin applications. This allows convenient expansion of the memory of desktop computers, servers, workstations, and applications integrated into communications and industrial equipment. The reduced profile reduces the space on the board. They are also equipped with low-impedance contacts, which minimize the power consumption in the devices. In addition to many installations of this type, the outputs are compatible with the standard DIMM to optimize airflow.

Although DDR4 will take a more substantial path that will provide the basis for massive technological innovation, it will not stop for the time being. The technology keeps jumping. The next DDR5 industry standard, which offers even better speed and performance, is currently designed for use in graphics cards, game consoles, and high-performance computers.
