4-Byte Fetch is shown on 8-bit bus, burst can be 2 to 16 bytes.
Data bus is sampled on the rising edge of clock 6, and every three clocks thereafter (clocks 6, 9, 12, and 15 in this example).

4-Byte Fetch is shown on 8-bit bus, burst can be 2 to 16 bytes.
To meet Hold Time, EDO DRAM drives Data until OE rises, or until a new falling edge of CAS.
Data bus is sampled on the rising edge of clock 6, and every three clocks thereafter (clocks 6, 8, 10, and 12 in this example).
