Understanding DDR4 AC Timing Parametrics
DDR4 speeds require key AC timing parameters
such a tDIVW, tDS, tDH to be defined and measured in a new way. The traditional
assumptions that as long as tDS/tDH were met there would be zero errors have
never actually been true and have forced costly and time-consuming over-design
of controllers, DRAMS and systems. DDR4 addresses this issue head on by
accounting for real-world random and deterministic jitter at a Bit Error Rate
(BER) that assures system stability while eliminating the need for expensive
over-design. This session will explain the new AC parameters in depth and show
you how to measure them, allowing accurate device characterization and system
validation without costly timing surprises at system integration.
