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 Standard 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).

This document describes design of test structures needed to assess the reliability of aluminum-copper, refractory metal barrier interconnect systems. This includes any metal interconnect system where a refractory metal barrier or other barrier material prevents the flow of aluminum and/or copper metal ions from moving between interconnect layers. This document is not intended to show design of test structures to assess aluminum or aluminum-copper alloy systems, without barriers to Al and Cu ion movement, nor for Cu only metal systems. Some total interconnect systems might not include barrier materials on all metal layers. The structures in this standard are designed for cases where a barrier material separates two Al or Al alloy metal layers. The purpose of this document is to describe the design of test structures needed to assess electromigration (EM) and stress-induced-void (SIV) reliability of AlCu barrier metal systems.

This device is a one-chip spectrum analyzer that operates in the frequency range from 1 to 2 GHz.It requires no external components except some filtering of the voltage supply (one inductor, one bypass capacitor).
The frequency of the VCO is adjusted by an internal DAC. No PLL loop is used to lock the VCO to a reference frequency. A counter is used to determine the VCO frequency.

This test is used to determine the effects of bias conditions and temperature on solid state devices over time. It simulates the devices’ operating condition in an accelerated way, and is primarily for device qualification and reliability monitoring. A form of high temperature bias life using a short duration, popularly known as burn-in, may be used to screen for infant mortality related failures. The detailed use and application of burn-in is outside the scope of this document.
