characteristics, packages, and ball/signal assignments. The purpose of this specification is to define the
minimum set of requirements for JEDEC compliant 4 Gb through 32 Gb for x16x2channel SDRAM
devices. This document was created using aspects of the following standards: DDR2 (JESD79-2), DDR3
(JESD79-3), DDR4 (JESD79-4), LPDDR (JESD209), LPDDR2 (JESD209-2) and LPDDR3 (JESD209-3).
