| LOW POWER DOUBLE DATA RATE (LPDDR) SDRAM STANDARD | JESD209B | Feb 2010 |
This standard defines the Low Power Double Data Rate (LPDDR) SDRAM, including features, functionality, AC and DC characteristics, packages, and pin assignments. This scope may be expanded in future to also include other higher density devices. The purpose of this document is to define the minimum set of requirements for JEDEC compliant 64Mb through 2Gb for x16 and x32 Low Power Double Data Rate SDRAM devices. System designs based on the required aspects of this standard will be supported by all LPDDR SDRAM vendors providing compliant devices. (JESD209 was originally numbered as JESD79-4 May 2006 to August 2007, corrected to JESD209 09/17/2007). Committee(s): JC-42.3, JC-42.6 Free download. Registration or login required. |

| DRIVER SPECIFICATIONS FOR 1.8 V POWER SUPPLY POINT-TO-POINT DRIVERS | JESD8-17 | Nov 2004 |
This material is intended to be reflected in supplier specifications for point to point DDR devices ranging from 400 Mb/s to 800 Mb/s operation. It is a method to specify driver impedance with something other than a number that does not nec-essarily define how it operates in a real net This standard addresses this issue using net lengths and specifies how much uncertainty can exist in the data for each speed supported.
