This standard establishes methods for calculating failure rates in units of FITs by using data in varying degrees of detail such that results can be obtained from almost any data set. The objective is to provide a reference to the way failure rates are calculated.

This standard is a minor editorial revision to JESD403-1, it defines the assumptions for the system management bus for next generation memory solutions; covering the interface protocol, use of hub devices, and voltages appropriate to these usages. Item 2260.37B.

This document defines the LPDDR5 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 x16 one channel SDRAM device and x8 one channel SDRAM device. LPDDR5 device density ranges from 2 Gb through 32 Gb. This document was created using aspects of the following standards: DDR2 (JESD79-2), DDR3 (JESD79-3), DDR4 (JESD79-4), LPDDR (JESD209), LPDDR2 (JESD209-2), LPDDR3 (JESD209-3) and LPDDR4 (JESD209-4). Item  1854.99B.

The Unbiased HAST is performed for the purpose of evaluating the reliability of nonhermetic packaged solid-state devices in humid environments. It is a highly accelerated test which employs temperature and humidity under noncondensing conditions to accelerate the penetration of moisture through the external protective material (encapsulant or seal) or along the interface between the external protective material and the metallic conductors that pass through it. Bias is not applied in this test to ensure the failure mechanisms potentially overshadowed by bias can be uncovered (e.g., galvanic corrosion). This test is used to identify failure mechanisms internal to the package and is destructive.

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.

This document is intended to guide device manufacturers in developing datasheets and to device customers in understanding datasheet entries.

The scope of this document covers SiC-based PECS devices having a gate dielectric region biased to turn devices on and off. This typically refers to MOS devices such as MOSFETs and IGBTs. In this document, only NMOS devices are discussed as these are dominant for power device applications; however, the procedures apply to PMOS devices as well.

Item 142.01, 142.02.This section provides electrical interface items related to Multi-Chip Packages (MCP) and Stacked-Chip Scale Packages (SCSP) of mixed memory technologies including Flash (NOR and NAND), SRAM, PSRAM, LPDRAM, USF, etc. These items include die-on-die stacking within a single encapsulated package, package-on-package or module-in-package technologies, etc. The Section also contains Silicon Pad Sequence information for the various memory technologies to aid in the design and electrical optimization of the memory sub-system or complete memory stacked solution. 

A DRAM rowhammer security exploit is a serious threat to cloud service providers, data centers, laptops, smart phones, self-driving cars and IoT devices. Hardware research and development will take time. DRAM components, DRAM DIMMs, System-on-chip (SoC), chipsets and system products have their own design cycle time and overall life time. This publication recommends best practices to mitigate the security risks from rowhammer attacks. Item 1866.02.

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

This document defines the Graphics Double Data Rate 6 (GDDR6) Synchronous Graphics Random Access Memory (SGRAM) specification, including features, functionality, package, and pin assignments.  The purpose of this Specification is to define the minimum set of requirements for 8 Gb through 16 Gb x16 dual channel GDDR6 SGRAM devices. System designs based on the required aspects of this standard will be supported by all GDDR6 SGRAM vendors providing compatible devices. Some aspects of the GDDR6 standard such  as AC timings and capacitance values were not standardized. Some features are optional and therefore may vary among vendors. In all cases, vendor data sheets should be consulted for specifics. This document was created based on some aspects of the GDDR5 Standard (JESD212). Item 1836.99E.

This document specifies the enclosure form factor which can be used with various type of SSD devices: outline of the top and bottom enclosure, three screw holes to mount the enclosure on the system, and two clamping holes in the top enclosure to lock to the connector. Item 318.06.

This standard identifies the best commercial practices for mitigating and/or avoiding counterfeit products by all manufacturers of electronic parts including, but not limited to original component manufacturers (OCMs), authorized aftermarket manufacturers, and other companies that manufacture electronic parts under their own logo, name, or trademark. The types of product this standard applies to is limited to monolithic microcircuits, hybrid microcircuits and discrete semiconductor products.

This version is a minor editorial adding Annex B that was left out of the original publication October 2020.An NVDIMM-P device is defined as a LRDIMM memory module which provides host controller access to DRAM and/or other memory devices such as persistent memory.  A transactional protocol is described for NVDIMM-P, which may be used on a DDR interface allowing operation of both standard DRAM modules and NVDIMM-P modules on the same channel. Item 2233.98K.

This document is intended for use in the GaN power semiconductor and related power electronic industries and provides guidelines for test methods and circuits to be used for continuous-switching tests of GaN power conversion devices.

This document, while establishing the complex nature of System Level ESD, proposes that an efficient ESD design can only be achieved when the interaction of the various components under ESD conditions are analyzed at the system level. This objective requires an appropriate characterization of the components and a methodology to assess the entire system using simulation data. This is applicable to system failures of different categories (such as hard, soft, and electromagnetic interference (EMI)). This type of systematic approach is long overdue and represents an advanced design approach which replaces the misconception, as discussed in detail in JEP161, that a system will be sufficiently robust if all components exceed a certain ESD level.
