This standard defines the Wide I/O specification, including features, functionality, AC and DC characteristics, packages, and micropillar signal assignments. This standard covers the following technologies: Wide I/O. The purpose of this standard is to define the minimum set of requirements for JEDEC compliant, 1 Gb through 32 Gb SDRAM (monolithic density) devices with 4, 128b wide channels using direct chip-to-chip attach methods between 1 to 4 memory devices and a controller device.

This standard is intended to cover the measurement of noise voltage in voltage regulator diodes in the reverse breakdown region. It describes noise voltage measurements at specified conditions, but may be used as a guide for making such measurements at other than specified conditions. Formerly known as RS-307 and/or EIA-307

This standard describes a functional specification of the Host Controller Interface (HCI) for Universal Flash Storage (UFS). The objective of UFSHCI is to provide a uniform interface method of accessing the UFS hardware capabilities so that a standard/common Driver can be provided for the Host Controller. The common Driver would work with UFS host controller from any vendor. This standard includes a description of the hardware/software interface between system software and the host controller hardware. It is intended for hardware designers, system builders and software developers. Item 205.06

This Unified Memory Extension standard is an extension to the UFSHCI standard, JESD223. The UFSHCI standard defines the interface between the UFS driver and the UFS host controller. In addition to the register interface, it defines data structures inside the system memory, which are used to exchange data, control and status information. Furthermore the UFSHCI standard defines the protocol layer structure and abstract entities within these layers. Unified Memory offers the possibility to move Device internal working memory into the system memory to reduce overall system cost and to improve Device performance. Item 203.25

The primary objective of this test standard is to specify the test cases for UFS device protocol conformance testing. This test standard provides test cases for checking the functions defined in the following target standard: JESD220. Universal Flash Storage (UFS) Standard version 1.1A. MIPI M-PHY and MIPI UniPro test cases are not in the scope of this document. Item 400.36

This standard defines DC interface parameters and test conditions for a family of non-terminated CMOS digital circuits intended for use over a wide power supply voltage range.  The standard bridges a number of existing JEDEC standards in the JESD8-x family to facilitate applications that operate over an ultra-wide power supply voltage range in order to achieve lower power dissipation or higher performance.

This standard is applicable to Thyristor Surge Protective Devices. It describes terms and definitions and explains methods for verifying device ratings and measuring device characteristics. The intended users of this standard are those interested in Thyristor Surge Protective Device characterization and rating verification. These devices are used primarily by the telecommunications industry to protect circuits from harmful overvoltages. The Thyristor Surge Protective Device (TSPD) is a semiconductor device that is finding widespread application in the telecommunication industry. The intent of this stand is to provide information on test methods that will reduce the possibility of disagreement and misunderstanding between TSPD vendors and users, and facilitate the determination of device interchangeability.
