Introduction to DDR3: Technology Overview and Performance Demonstration
Many will argue that the upheavals of the hardware world are a matter of routine, since almost every day we encounter one revolutionary development or another that claims to be able to completely change our technological perception. But these are only half-truths as the basis for most developments has remained unchanged over the years, despite the many minds engaged in the craft. Many patents actually originate in fairly old developments, and so does the situation with the idea behind the well-known DRAM technology, which was first introduced more than four decades ago. Despite the long time that has elapsed, the principle of operation remains basically the same - storing information (in a single bit size) in each capacitor, which represents one memory cell. In light of the current situation, there is no concrete factor trying to challenge the status of this patent, so the expectation is that this \ 'outdated \' technology will continue to be the cornerstone of the field of memory.
However, it is obvious that over the years many developments have been made on the same basic theory he had conceived at the time Dr Robert Dennard, And today we will actually look at the latest development in the lineage, DDR3 SDRAM technology. This is the third generation of the Double Data Rate line, which will introduce the traditional SDRAM technology by enabling the transmission of information in the ascending and descending portion of the signal sent in each clock cycle.
For many years, memories have been marked as the main bottleneck in the system. The transition to the second generation of DDR technology has generated many expectations, but these have been realized only in the past year and a half when it finally matured into a standard product in every system. Low frequencies initially and prices that are not suitable for most consumers, we have seen this year how high market models become common property, and at an unprecedented speed. The appetite also comes with the food, and today, at the end of the day of DDR2 technology, we are able to see models ready for operation at the 1250MHz frequency directly from the factory.
The need for such quick memories comes mainly from Core processors, which changed things (mainly for the Overclocks). The efficiency of the architecture foreshadowed a new and successful era in the field, which brought with it much higher bandwidth than expected due to the low multiplication of the processors. It is known that the higher the channel frequency, the faster memory is required, and this is apparently the fact that it stimulated chip manufacturers and memories to achieve new heights and realize the potential completely.
Today, it is safe to say that memories are long ago not the main bottleneck, but the spirit of change is blowing from the processor scene and the two leading manufacturers in the field are expected to release new processor series towards the end of this year and the beginning of next year (AMD already Released architecture to servers , But is expected to release compatible processors DDR3 To the private market only next year), requiring more system resources and, as a result, faster memories. Therefore, as in similar cases in the past, this time too, the development in this arena is followed by similar changes in the field of memories, which come after only three years to the third generation.
