*1:It is a guarantee value with being alone. 35ns.max garantees as follows:
td(BCLK-RAS) + tsu(DB-BCLK)
td(BCLK-CAS) + tsu(DB-BCLK)
td(BCLK-CAD) + tsu(DB-BCLK)
*2:It depends on operation frequency.

Measuring conditions
• VCC=5V±10%
• Input timing voltage
:Determined with VIH=2.5V, VIL=0.8V
• Output timing voltage
:Determined with VOH=2.0V, VOL=0.8V
