DDR Memory Design & Test

Double Data Rate (DDR) Synchronous Dynamic Random Access Memory (SDRAM) is implemented in several forms today – the original DDR (also called DDR1), DDR2 which improved performance and lowered power consumption, DDR3 with even better performance, and low-power DDR (LPDDR), that is targeted for mobile devices.

Agilent is an active member of JEDEC, with consistent participation in workshops and specification issues. These resources you find here will provide you with an overview of DDR design, understand the latest measurement techniques, and illustrate design and debug approaches.
