ADDENDUM CHANGES
The standard 128Mb SDRAM data sheets also per-
tain 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 specifi-
cations and functionality unless specified herein.
