CONFIGURATIONS FOR SOLID STATE MEMORIES:Status: Under RevisionSections in this document may be under revision at any time. |
JESD21-C | Jan 2003 |
This revision of JESD21 is substantially different from previous issues because it reflects advancement in semiconductor technology and computer design needs. A new class of memory devices, the multiport DRAM (MPDRAM) C also know as 'Video Ram' because of the most common application for the devices C is represented. A new family of SRAMs which addresses the increasing need for high speed is introduced. Additional families of devices in the SOJ and Zip packages are included. The material in this revision is organized primarily by function (ROM, EPROM, SRAM, DRAM, etc.) rather than by technology and word length. Pinouts for SIMM and DIMM are included along with presence detect schemes. A current set of terms has also been included. JESD21-C is a compilation of all memory device standards that have been developed by the JC-42 Committee and approved by the JEDEC BoD from September 1989 to present. This latest issue has changed to a loose-leaf format and comes in a three-ring binder so that new drawings can be added without requiring a new publication. Time of publication of the material is identified by release number, i.e., if marked Release 8, this item was approved and released in 1998, if marked Release 13, this item was approved and released in 2003.

CONSTANT-TEMPERATURE AGING METHOD TO CHARACTERIZE COPPER INTERCONNECT METALLIZATIONS FOR STRESS-INDUCED VOIDING |
JESD214.01 | Aug 2017 |
This document describes a constant temperature (isothermal) aging method for testing copper (Cu) metallization test structures on microelectronics wafers for susceptibility to stress-induced voiding (SIV). This method is to be conducted primarily at the wafer level of production during technology development, and the results are to be used for lifetime prediction and failure analysis. Under some conditions, the method may be applied to package-level testing. This method is not intended to check production lots for shipment, because of the long test time.

CYCLED TEMPERATURE HUMIDITY-BIAS WITH SURFACE CONDENSATION LIFE TEST |
JESD22-A100E | Nov 2020 |
The Cycled Temperature-humidity-bias Life Test is performed for the purpose of evaluating the reliability of nonhermetic packaged solid state devices in humid environments. It employs conditions of temperature cycling, humidity, and bias that 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. The Cycled Temperature-Humidity-Bias Life Test is typically performed on cavity packages (e.g., MQUADs, lidded ceramic pin grid arrays, etc.) as an alternative to JESD22-A101 or JESD22-A110.
