ARM has unveiled its latest DDR memory interface products, which feature improved support for SDRam requirements.
The expanded ARM Velocity DDR products are compliant with JEDEC standards for DDR, DDR2, Mobile DDR and GDDR3 SDRam.
The memory targets applications in mainstream PCs and servers with data rate speeds up to 800Mbps. According to the firm, the components are designed to be smaller with lower jitter performance than previous products.
ARM argued that there is a growing need for a mixed-signal technology to address issues such as signal and voltage integrity and impedance discontinuities.
In light of this ARM said that its latest Velocity DDR has added on-die termination for programmable termination to improve signal integrity and include advanced dynamic calibration, with higher DDR2 resolution of the input and output impedances ensuring more accurate impedance matching.
The Velocity DDR memory interfaces are available in a variety of standard CMOS processes on 130nm, 110nm, 90nm and 65nm nodes.
