* Parameters are characterized over recommended operating conditions.

** The tPD value in this table would equate to the 'Time-to-Vm' delay described in the post register timing specifications of the

PC133 registered DIMM Specification. The first value applies to DIMMs with nine SDRAM loads per register output, and the

second to DIMMs with eighteen SDRAM loads per register output. These values should serve as only an initial starting point,
