DDR SDRAM
DDR SDRAM 128Mb F-die (x4, x8)
Rev. 1.1 May. 2004
System Characteristics for DDR SDRAM
The following specification parameters are required in systems using DDR333, DDR266 devices to ensure proper system
performance. these characteristics are for system simulation purposes and are guaranteed by design.
