Addendum No. 3 to JESD79-3, 3D STACKED SDRAM

 JESD79-3-3 Dec 2013

This addendum to JESD79-3 defines the 3DS DDR3 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 compliant 8Gbit through 64Gbit x4 and x8 3DS DDR3 SDRAM devices. This document was created based on the E revision of the DDR standard (JESD79). Each aspect of the changes for 3DS DDR3 SDRAM operation was considered.
