Addendum No. 1 to JESD79-4, 3D STACKED DRAM |
JESD79-4-1B | Feb 2021 |
This document defines the 3DS DDR4 SDRAM specification, including features, functionalities, AC and DC characteristics, packages, and ball/signal assignments. The purpose of this specification is to define the minimum set of requirements for a compliant 8 Gbit through 128 Gbit for x4, x8 3DS DDR4 SDRAM devices. This addendum was created based on the JESD79-4 DDR4 SDRAM specification. Each aspect of the changes for 3DS DDR4 SDRAM operation was considered. Item 1727.58G Committee(s): JC-42.3C Free download.
