DDR3 Development History

DDR3 Development History

2002 DDR3 declared

As early as June 28, 2002, JEDEC announced the start of the development of DDR3 memory standards, but from the 2006 situation, DDR2 has only just begun to popularize, DDR3 standard is even not seen even the shadow. However, many manufacturers have come up with their own DDR3 solutions, have announced the successful development of the DDR3 memory chip, from which we can feel like DDR3 approaching. Judging from the fact that there are chips that can be produced, the standard design work for DDR3 is nearing completion.

2008 DDR3 market share will reach 55%

Semiconductor market research firm iSuppli predicts that DDR3 memory will replace DDR2 as the mainstream product in the market in 2008. iSuppli believes that DDR3's market share will reach 55% at that time. As of the end of November 2008, this expectation is still relatively accurate. The market has occupied a lot of DDR3 memory with operating frequencies of 1066, 1333, 1600, and even 2000 MHz. There are two types of interfaces, 204 and 240 PIN. However, in terms of specific designs, the basic architecture of DDR3 and DDR2 is not fundamentally different. From a certain point of view, DDR3 is the product of the limitations that were faced in order to solve the development of DDR2.

In 2009, the capacity of a single PC memory has reached a staggering 32GB

In the end of the winter of 2009, Samsung officially launched the world's largest single-density DDR3 chip. Based on a 50-nanometer manufacturing process, pushing single-cell capacity to 4Gb finally enabled us to enter the 64-bit era faster. The capacity of a single PC memory stick has reached a staggering 32GB. The new chip consumes 40% less power than the previous DDR3 chip.

Secondly, this cleared the way for the listing of a single 32GB memory module. The first 32GB of RDIMM memory available on the market was used for double-sided packaging in the server area (each side consists of 4×4G DDR3 chips), and it also faces the desktop market. Provides 8G of UDIMM memory for workstations and PC platforms, as well as 8GB of SO-DIMM notebook memory. The new low-power DDR3 memory is designed to operate at 1.35V, which is approximately 20% lower power than the previous 1.5V DDR3 chip, while maximizing throughput to 1.6Gbps.

In addition, the price of DDR2 may still be weak, I wonder if my notebook should be upgraded to DDR2 4GB? According to IDC's forecast DDR3 memory market share from the target 29% to reach 72% in 2011.
