Ever since the development of different PCs to the modern smartphones, memory standards have always been a factor determining the performance of the system as a whole. Over time, it has gone through constant updates from SDR, or Single Data Rate RAM found in old computers of the past era, to the recent DDR or Double Data Rate.
From the early days, one of the significant factors affecting the performance of a device was the inability of memory speed to match with that of the processor speeds. The introduction of double data rate was a revolutionary move, as this showcased the memory bus performances in line with the processor speeds. This resulted in the optimum performance of the system.
The shift to SRAM and DDR went through constant updates to meet the demand of ultra-modern innovations in a fast pace. Starting with DDR SRAM of 200 MHz in early 2001, to the 400 MHz DDR2 in 2002, it was just the beginning of an impressive journey. By the end of 2007, DDR2 was able to meet memory speeds up to 1,066MHz. 2009 saw even better levels with the introduction of DDR3
Today the latest progeny of the series DDR4 has captured the market with even better performance and robust control features. In addition to performance and speeds, it features improved energy economy for enterprise, tablet, microserver and ultrathin client applications.
This novel solution has many proven advantages over its predecessors. This is one primary reason most applications are rolling out the previous version to update with DDR4. It comes with a data rate of 2 GB to 16 GB enabling large capacity subsystems. When compared to a maximum of 16 GB per DIMM of DDR3, the DDR4 standard allows for DIMMs of capacity, up to 64 GB.
There are many types of DDR4 sockets and modules available in the market. The Ultra Low Profile (ULP) vertical DIMM sockets facilitate an ideal solution for ultra-thin applications. This help with convenient memory expansion in desktop PCs, servers, workstations, embedded applications in communications and industrial equipment. The overall reduced profile helps in reducing board space. These are also equipped with low resistance contacts that minimize power consumption within the hardware. In addition to offering many such facilities, the sockets are compatible with standard DIMM module to help optimize airflow.
Though DDR4 opens a more substantial avenue which lays the basis for massive technological innovations, it will not stop there, yet. The technology is also leaping to its further advancements. The upcoming DDR5 industry standard which provides even better speed and performance are presently designed for use in graphics cards, game consoles, and high-performance computation.
