The manufacturers identification code is defined by one or more 8 bit fields, each consisting of 7 data bits plus 1 odd parity bit. The manufacturers identification code is assigned, maintained and updated by the JEDEC Office. The intent of this identification code is that it may be used whenever a digital field is required, e.g., hardware, software, documentation, etc. To make a request for an ID Code please go to http://www.jedec.org/Home/MIDCODE_request.cfm

Item 11.10-457

These guidelines apply to GaAs Monolithic Microwave Integrated Circuits (MMICs) and their individual component building blocks, such as GaAs Metal-Semiconductor Field Effect Transistors (MESFETs), Pseudomorphic High Electron Mobility Transistors (PHEMTs), Heterojunction Bipolar Transistors (HBTs), resistors, and capacitors.  While the procedure described in this document may be applied to other semiconductor technologies, especially those used in RF and microwave frequency analog applications, it is primarily intended for technologies based on GaAs and related III-V material systems (InP, AlGaAs, InGaAs, InGaP, GaN, etc). 

This section covers DDR2 DIMM labels.

The HBM DRAM is tightly coupled to the host compute die with a distributed interface. The interface is divided into independent channels. Each channel is completely independent of one another. Channels are not necessarily synchronous to each other. The HBM DRAM uses a wide-interface architecture to achieve high-speed, low-power operation. The HBM DRAM uses differential clock CK_t/CK_c. Commands are registered at the rising edge of CK_t, CK_c. Each channel interface maintains a 128b data bus operating at DDR data rates. Also available for designer ease of use is HBM Ballout Spreadsheet.

Item 1797.99J.

This stress test is intended to determine the ability of an EEPROM integrated circuit or an integrated circuit with an EEPROM module (such as a microprocessor) to sustain repeated data changes without failure (program/erase endurance) and to retain data for the expected life of the EEPROM (data retention). This Standard specifies the procedural requirements for performing valid endurance and retention tests based on a qualification specification. Endurance and retention qualification specifications (for cycle counts, durations, temperatures, and sample sizes) are specified in JESD47 or may be developed using knowledge-based methods as in JESD94.
