No Preview Available ! Am50DL128BH Data Sheet July 2003 The following document specifies Spansion memory products that are now offered by both Advanced Micro Devices and Fujitsu. Although the document is marked with the name of the company that orig- inally developed the specification, these products will be offered to customers of both AMD and Fujitsu. Continuity of Specifications There is no change to this datasheet as a result of offering the device as a Spansion product. Any changes that have been made are the result of normal datasheet improvement and are noted in the document revision summary, where supported. Future routine revisions will occur when appropriate, and changes will be noted in a revision summary. Continuity of Ordering Part Numbers AMD and Fujitsu continue to support existing part numbers beginning with “Am” and “MBM”. To order these products, please use only the Ordering Part Numbers listed in this document. For More Information Please contact your local AMD or Fujitsu sales office for additional information about Spansion memory solutions.
