The purpose of this standard is to provide guidelines under which data sheets for semiconductor memories are to be generated. Adherence to these guidelines should produce data sheets that are concise and that consistently define the operation and characteristics of semiconductor memory devices. It is not intended that data sheets already in existence be revised specifically to conform to this format. However, data sheets being generated for the first time for new products should adhere to this standard. As part of the standard, a nomenclature for memory devices is presented. This nomenclature includes a format for defining electrical parameters and two alternative formats for timing parameters. The first timing parameter format uses a FROM-TO concept for explicitly defining most timing parameters that are needed to specify complex memory devices. The alternate form utilizes a functional description approach. Recommendations are also made for a uniform pin naming glossary of terms.
