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.

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.
