ADDENDUM CHANGES
The standard 128Mb SDRAM data sheets also pertain to the x16 device and should be referenced for a complete description of SDRAM functionality and operating modes. However, to meet the faster speed grades, some of the AC timing parameters are slightly different. This addendum data sheet will concentrate on the key differences required to support the enhanced speeds.
The Micron 128Mb data sheet provides full specifications and functionality unless specified herein.
