1、JEDEC STANDARD Low Power Double Date Rate 4 (LPDDR4) JESD209-4B (Revision of JESD209-4A, November 2015) FEBRUARY 2017 JEDEC SOLID STATE TECHNOLOGY ASSOCIATION NOTICE JEDEC standards and publications contain material that has been prepared, reviewed, and approved through the JEDEC Board of Directors
2、level and subsequently reviewed and approved by the JEDEC legal counsel. JEDEC standards and publications are designed to serve the public interest through eliminating misunderstandings between manufacturers and purchasers, facilitating interchangeability and improvement of products, and assisting t
3、he purchaser in selecting and obtaining with minimum delay the proper product for use by those other than JEDEC members, whether the standard is to be used either domestically or internationally. JEDEC standards and publications are adopted without regard to whether or not their adoption may involve
4、 patents or articles, materials, or processes. By such action JEDEC does not assume any liability to any patent owner, nor does it assume any obligation whatever to parties adopting the JEDEC standards or publications. The information included in JEDEC standards and publications represents a sound a
5、pproach to product specification and application, principally from the solid state device manufacturer viewpoint. Within the JEDEC organization there are procedures whereby a JEDEC standard or publication may be further processed and ultimately become an ANSI standard. No claims to be in conformance
6、 with this standard may be made unless all requirements stated in the standard are met. Inquiries, comments, and suggestions relative to the content of this JEDEC standard or publication should be addressed to JEDEC at the address below, or refer to www.jedec.org under Standards and Documents for al

10、on Low Power Memories.)1 ScopeThis document defines the LPDDR4 standard, 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 JEDEC compliant 16 bit per channel SDRA
11、M device with either one or two channels. LPDDR4 dual channel device density ranges from 4 Gb through 32 Gb and single channel density ranges from 2 Gb through 16 Gb. This document was created using aspects of the following standards: DDR2 (JESD79-2), DDR3 (JESD79-3), DDR4 (JESD79-4), LPDDR (JESD209
12、), LPDDR2 (JESD209-2) and LPDDR3 (JESD209-3).Each aspect of the standard was considered and approved by committee ballot(s). The accumulation of these ballots was then incorporated to prepare the LPDDR4 standard.JEDEC Standard No. 209-4BPage 22 Package ballout and Pin definition2.1 Pad Order 2.1.1 P
