NOTICE
JEDEC standards and publications contain material that has been prepared, reviewed, and
approved through the JEDEC Board of Directors level and subsequently reviewed and approved
by the JEDEC legal counsel.
JEDEC standards and publications are designed to serve the public interest through eliminating
misunderstandings between manufacturers and purchasers, facilitating interchangeability and
improvement of products, and assisting the purchaser in selecting and obtaining with minimum
delay the proper product for use by those other than JEDEC members, whether the standard is to
be used either domestically or internationally.
JEDEC standards and publications are adopted without regard to whether or not their adoption
may involve patents or articles, materials, or processes. By such action JEDEC does not assume
any liability to any patent owner, nor does it assume any obligation whatever to parties adopting
the JEDEC standards or publications.
The information included in JEDEC standards and publications represents a sound approach to
product specification and application, principally from the solid state device manufacturer
viewpoint. Within the JEDEC organization there are procedures whereby a JEDEC standard or
publication may be further processed and ultimately become an ANSI standard.
No claims to be in conformance with this standard may be made unless all requirements stated in
the standard are met.

publication should be addressed to JEDEC at the address below, or www.jedec.org under

STANDARD MANUFACTURER’S IDENTIFICATION CODE
(From JEDEC Board Ballot JCB-94-02, formulated under the cognizance of JC-42.3
Subcommittee on RAM Memories.)
1 Intent
The intent of this identification code is that it may be used whenever a digital field is required,
e.g., hardware, software, documentation, etc.
2 Scope
The manufacturer’s identification code is defined by one or more eight (8) bit fields, each
consisting of seven (7) data bits plus one (1) odd parity bit. The manufacturer’s identification
code as shown in Table 1, is assigned, maintained and updated by the JEDEC office. It is a
single field, limiting the possible number of vendors to 126. To expand the maximum number of
identification codes, a continuation scheme has been defined. The code 7F, as shown in Table 1,
indicates that the manufacturer’s code is beyond the limit of this field and the next sequential
manufacturer’s identification field is used. Multiple continuation fields are permitted and when
used, shall comprise of the identification code.
3 Additions to Table 1
The identification code list is not a fixed listing. Any company can be added to the list by
making a request to the JEDEC office at (703) 907-7540. The present list is complete as of
February 28, 2013. Updates to the list will be made periodically and Table 1 will be modified
accordingly.
