JEDEC Solid State Technology Association
The JEDEC Solid State Technology Association ( JEDEC for short ) is an American organization for the standardization of semiconductors . It was previously called the Joint Electron Device Engineering Council .
JEDEC was a member of the Electronic Industries Alliance (EIA), which was dissolved in 2010, and has more than 300 semiconductor manufacturers as members.
history
The history of JEDEC begins in 1924 with the founding of the Associated Radio Manufacturers (ARM) , which offered 50 radio producers a body to standardize all aspects of radio production (including the price cartel ) in Chicago . A few weeks later, the ARM was renamed the Radio Manufacturers Association (RMA) , the forerunner of the EIA. In 1926 another organization, the National Association of Electrical Manufacturers (NEMA), was founded, which together with the RMA founded the Joint Electron Tube Engineering Council (JETEC) in 1944 . In 1950, in response to the growing popularity of television , the RMA became the Radio Television Manufacturers Association (RTMA) , which also dealt with semiconductors . In 1953 the next adaptation to the development followed by changing the name to Radio Electronics Television Manufacturers Association (RETMA) . In 1956 there was a department that only dealt with semiconductors. In 1957 RETMA became the Electronic Industries Alliance (EIA) to document the all-encompassing claim to electronics . In 1958, JETEC was split into two bodies and renamed Joint Electron Devices Engineering Councils (JEDEC) , one of which dealt with conventional tubes as the JEDEC Tube Council and the other as the JEDEC Semiconductor Council with semiconductors. After a sub-committee had taken care of microelectronics since 1965 , both were merged in 1970 to form the Solid State Products Division (SSPD) . In 1977 the tubes were spun off, which became the Tube Electron Panel Advisory Council (TEPAC) . The majority of the councils were history, but the NEMA withdrew from the funding.
In March 1998 the body was transferred to a department of the EIA and renamed the JEDEC Solid State Technology Division . In November of the same year, the department became an equal company with the current final name of JEDEC Solid State Technology Association . Under the umbrella of the EIA, it is on an equal footing with companies such as the Consumer Electronics Association (CEA), Telecommunications Industry Association (TIA), Electronic Components and Assemblies, Equipment and Supplies Association (ECA) and Government Division and the Electronic Information Group (GEIA).
tasks
JEDEC has taken on a multitude of different tasks, including:
- Standardization of certain main memory components ( RAM ) for computers , such as SDRAM or DDR-SDRAM
- Standardization of physical and logical digital interfaces of electronic circuits and assemblies
- Standardization of housing shapes for electronic components
- Quality standards with test regulations
- Standardization for new technologies of lead-free production (see RoHS guidelines )
- JEDEX sales shows for electronics manufacturers
- Standardization for Solid State Drives
File format
JEDEC is also the standard data format for programming GAL and PAL semiconductors. It is described in the JEDEC standard JESD3 and has the file extension .jed .
The files are similar to the Intel HEX format. They are ASCII text files that can be converted to HEX format. Essentially, the files contain the matrix of programmable fuses.
