Previously I introduced DDR4 for space applications (see “Fast DDR4 SDRAM to enable the new space age”) offering 4 GB of volatile storage at a clock frequency up to 1.2 GHz and a data rate of 2.4 GT/s ...

DDR SDRAM technology has reached its 4th generation. The DDR4 SDRAM interface achieves a maximum data rate of 3.6Gbps per bit (i.e., clock rate of 1.8GHz). There are four key challenges in designing ...

PCB and embedded systems designers are scratching their heads these days, facing some uncertainty as they start mapping out the move from DDR3 SDRAM to DDR4. Routing DDR2 signals on a PCB was tough ...
