This standard defines standard specifications of DC interface parameters, switching parameters, and test loading for definition of the SSTUB32865 registered buffer with parity for 2 rank by 4 or similar high-density DDR2 RDIMM applications. The SSTUB32865 is identical in functionality to the SSTU32865 but specifies tighter timing characteristics and a higher application frequency of up to 410 MHz.

The purpose is to provide a standard for the SSTUB32865 (see Note) logic device, for uniformity, multiplicity of sources, elimination of confusion, ease of device specification, and ease of use.

NOTE The designation SSTUB32865 refers to the part designation of a series of commercial logic parts common in the industry. This number is normally preceded by a series of manufacturer specific characters to make up a complete part designation.
