DDR3

Since JEDEC published the DDR3 SDRAM specification in 2007, DDR3 SDRAM is one of the most common DRAM technologies in industrial, embedded as well as a variety of other applications. However, many manufacturers have announced to discontinue DDR3 components.

Thanks to our broad linecard, we still offer a broad range of DDR3 in a variety of configurations from these manufacturers: Chiplus, ESMT, Etron, Intelligent Memory, Nanya, and Winbond.

DDR3 vs. DDR2

Fast performance: Typical DDR3 runs up to 1066 MHz vs 533 MHz for DDR2.

Energy Efficient: 1.5 V (1.35 V for DDR3L) for DDR3, helping reduce power consumption and heat generation.

Improved Data Handling: Features 8-bit prefetch and up to 8 bank groups, allowing better everyday tasks and throughput for demanding applications.

Features	DDR3	DDR2
Speed	1066 MHz	533 MHz
Voltage	1.5V/1.35V	1.8V
Typical Densities	1/2/4/8 Gb	256/512Mb - 1/2 Gb
Banks	8	4
Prefetch	8 Bit	4 Bit

Applications

Industrial

Smart TV

Set Top Box (STB), Printers, POS Machine

Surveillance camera

Power equipment

FAQs:

Can I replace DDR3 with DDR4?

No, DDR3 is not compatible withDDR4 due to different pin configurations and electrical standards:

different pin layout (240 pins vs. 288 pins)
different voltage (1.5V vs. 1.2V)
different signal specification

To upgrade from DDR3 to DDR4 you need:

a DDR4 compatible CPU and motherboard
a complete platform re-design

Why is DDR3 still used in industrial systems?

DDR3 remains popular due to its long-term availability, low power consumption, and compatibility with legacy systems.

What is the most common DDR3 configuration used in industrial environments?

Our customers are most interested in these DDR3 features: 8Gb, DDR3-1600 to DDR3-1866, 1.5V or 1.35V (DDR3L), x8 / x16 interface, industrial temperature range (−40°C~85°C or up to 95°C for extended versions).

What is the long-term outlook for DDR3 beyond 2030?

DDR3 demand will be extremely niche beyond 2030. Processor ecosystems are already phasing out DDR3. Support will only remain where customers are willing to commit to wafer banking or custom long-tail supply programs. The availabilty beyond 2030 will be limited to legacy maintenance markets (industrial, defense, aerospace).
