Introduction to the DDR3 RAM Including Its History and Specs

Then post from MiniTool has gathered much information about the DDR3 RAM, for example, its history.

Since 2007, it has been in use.

Keep reading and then you could know much information about DDR3 RAM in this post offered byMiniTool.

64-bit data is transmitted through each memory module at a time.

All AMD CPUs correctly support the full specifications of 16 GiB DDR3 DIMMs.

History

In February 2005, Samsung released the first prototype of the DDR3 memory chip.

Samsung played an important role in the development and standardization of DDR3.

In 2007, DDR3 was officially launched.

In September 2012, the DDR4 RAM, the successor of the DDR3 RAM, was released.

Compared with DDR2 RAM, DDR3 RAM consumes less power.

The 1.5 V supply voltage works well with the 90-nanometer fabrication technology used in the original DDR3 chips.

Some manufacturers have also proposed the use of dual-gate transistors to reduce current leakage.

Another advantage is that its prefetch buffer is 8-burst-deep.

In contrast, DDR2s prefetch buffer is 4-burst-deep, while DDRs prefetch buffer is 2-burst-deep.

This advantage is an enabling technology in DDR3 transfer speed.

DDR3 dual-inline memory modules (DIMMs) have 240 pins and are not electrically compatible with DDR2.

The key notch locations in DDR2 and DDR3 DIMMs are different, preventing them from being accidentally replaced.

The CPUs integrated memory controller can then use any of them.

DDR3 latencies are numerically higher because the I/O bus clock cycles that measure them are shorter.

The actual time interval is similar to the DDR2 delay, about 10 ns.

Dells Power Advisor calculates that each 4 GB ECC DDR1333 RDIMM consumes approximately 4W.
