Crossing the Digital-Analog Divide - White Paper
This white paper helps to better understand how to cope with the physical nature of signals that we might prefer to think of as bits, nibbles and bytes, let's start with an ideal digital waveform.

Maximizing DDR BGA probe Bandwidth for Superior Signal Fidelity
The use of BGA probes for probing DDR DRAM is becoming more popular and almost a requirement as memory design gets more complex and compact and data rate gets higher. DDR3 and DDR4 data rate is increasing from 800MT/s to possibly 3200MT/s.

DDR Probing for Physical Layer and Functional Testing
Probing is the key to accessing signals and validating your designs. Although you may normally probe at signal vias or designed-in probe points, for DDR these do not always provide good signal integrity.
