Non-members may obtain individual Assurance/Disclosure forms by requesting them from the JEDEC office. Committee(s): JC-42.4 Free download. Registration or login required.
Secure Serial Flash Bus Transactions Release Number: Version 1.0	JESD254	Dec 2022
This standard describes SPI bus transactions intended to support Secure Flash operation on a serial memory device. The on-chip SFDP database described in JESD216 has been revised to include details about the secure transactions. This ballot does not describe the SFDP revisions or the secure packet structure. A list of RAND License Assurance/Disclosure Forms is available to JEDEC members on the restricted Members' website. Non-members may obtain individual Assurance/Disclosure forms by requesting them from the JEDEC office. Committee(s): JC-42, JC-42.4 Free download. Registration or login required.
Serial NOR Security Hardware Abstraction Layer	JESD261	Nov 2022
This standard provides a comprehensive definition of the NOR cryptographic security hardware abstraction layer (HAL). It also provides design guidelines and reference software to reduce design-in overhead and facilitate the second sourcing of secure memory devices. It does not attempt to standardize any other interaction to the NOR device that is not related to cryptographic security functionality within the device. A list of RAND License Assurance/Disclosure Forms is available to JEDEC members on the restricted Members' website. Non-members may obtain individual Assurance/Disclosure forms by requesting them from the JEDEC office. Committee(s): JC-42.4 Free download. Registration or login required.
DICTIONARY OF TERMS FOR SOLID-STATE TECHNOLOGY, 7th Edition	JESD88G	Mar 2025
This reference for technical writers and educators, manufacturers, and buyers and users of discrete solid state devices is now available. It should aid the technical committees of JEDEC in the avoidance of multiple definitions and reduce the proliferation of redundant definitions. The long-term goal is to include definitions from all JEDEC publications and standards. Each of the approximately two thousand entries is referenced to its source publication, and an annex listing the names of the source publications and their releases dates is included. All entries were reviewed for punctuation, grammar, and clarity, as well as accuracy, and reworded if such was considered warranted. The purpose of this dictionary is to promote the uniform use of terms, definitions, abbreviations, and symbols throughout the solid state industry A list of RAND License Assurance/Disclosure Forms is available to JEDEC members on the restricted Members' website. Non-members may obtain individual Assurance/Disclosure forms by requesting them from the JEDEC office. Committee(s): JC-10 Free download. Registration or login required.
EXPANDED SERIAL PERIPHERAL INTERFACE (xSPI) FOR NONVOLATILE MEMORY DEVICES	JESD251C	May 2022
This standard specifies the eXpanded Serial Peripheral Interface (xSPI) for Non Volatile Memory Devices, which provides high data throughput, low signal count, and limited backward compatibility with legacy Serial Peripheral Interface (SPI) devices. It is primarily for use in computing, automotive, Internet Of Things (IOT), embedded systems and mobile systems, between host processing and peripheral devices. The xSPI electrical interface can deliver up to 400 MBytes per second raw data throughput. Item 1775.74. A list of RAND License Assurance/Disclosure Forms is available to JEDEC members on the restricted Members' website. Non-members may obtain individual Assurance/Disclosure forms by requesting them from the JEDEC office. Committee(s): JC-42.4 Free download. Registration or login required.
SERIAL FLASH RESET SIGNALING PROTOCOL	JESD252.01	Apr 2021
This standard is intended for use by SoC, ASIC, ASSP, and FPGA developers or vendors interested in incorporating a signaling protocol for hardware resetting the Serial Flash device. In is also intended for use by peripheral developers or vendors interested in providing Serial Flash devices compliant with the standard. This standard defines a signaling protocol that allows the host to reset the slaved Serial Flash device without a dedicated hardware reset pin. Item 1775.06. A list of RAND License Assurance/Disclosure Forms is available to JEDEC members on the restricted Members' website. Non-members may obtain individual Assurance/Disclosure forms by requesting them from the JEDEC office. Committee(s): JC-42.4 Free download. Registration or login required.
REPLAY PROTECTED MONOTONIC COUNTER (RPMC) FOR SERIAL FLASH DEVICES	JESD260	Apr 2021
This document provides the requirements for an additional block called as Replay Protection Monotonic Counter. (RPMC) Replay Protection provides a building block towards providing additional security. This block requires modifications in both a Serial Flash device and Serial Flash Controller. The standard defines new commands for Replay Protected Monotonic Counter operations. A device that supports RPMC can support these new commands as defined in this standard. A list of RAND License Assurance/Disclosure Forms is available to JEDEC members on the restricted Members' website. Non-members may obtain individual Assurance/Disclosure forms by requesting them from the JEDEC office. Committee(s): JC-42.4 Free download. Registration or login required.
SPI Safety Extensions (CRC) for Non Volatile SPI Flash Memories (QPI and xSPI)	JESD255	Mar 2024
The JESD255 document defines CRC modes supported with 8-bit aligned and 16-bit aligned data transactions. It is limited to logical bus transactions and does not cover the electrical properties of the IO bus. A list of RAND License Assurance/Disclosure Forms is available to JEDEC members on the restricted Members' website. Non-members may obtain individual Assurance/Disclosure forms by requesting them from the JEDEC office. Committee(s): JC-42, JC-42.4 Free download. Registration or login required.
Low Power Double Data Rate Interface for Non-Volatile Memory (LPDDR4X-NVM) Standard	JESD326-4	Nov 2024
This standard defines the Low Power Double Data Rate interface for Non-Volatile Memory (LPDDR4XNVM) Standard. This standard describes 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 single channel LPDDR4X-NVM device. LPDDR4X-NVM density ranges from 128Mb through 32Gb.
