1 About this document
This document provides general hardware and layout
considerations and guidelines for hardware engineers
implementing a DDR4 memory subsystem.
The rules and recommendations in this document serve as an
initial baseline for board designers to begin their specific
implementations, such as fly-by memory topology.
NOTE
It is strongly recommended that the board
designer verifies that all aspects, such as
signal integrity, electrical timings, and so
on, are addressed by using simulation
models before board fabrication.
