Webful DDR4 high-speed design will require the use of these new features and they should not be overlooked. The Micron DDR4 data sheet provides in-depth explanation of these features. As the DRAM’s operating clock rates have steadily increased, doubling with each DDR technology increment, DRAM training/calibration has gone from being a luxury in DDR WebTo achieve the same data payload as a DDR4 module per transaction with the subchannel module layout, the DDR5 default burst length (BL) has increased from 8 to 16. The doubling of the BL implies a halving of data inputs/outputs (I/Os) required to fulfill the same amount of data for a given system access size.
