Note: 1. All DDR2 SDRAM commands are dened by states of CS#, RAS#, CAS#, WE#, and CKE at the rising edge of the clock.
2. Bank addresses (BA) BA0–BA2 determine which bank is to be operated upon. BA during a LM command selects which mode register is programmed.
3. The power-down mode does not perform any REFRESH operations. The duration of power-down is therefore limited by the refresh requirements outlined in the AC
parametric section.
4. The state of ODT does not affect the states described in this table. The ODT function is not available during self refresh. See “On-Die Termination (ODT)” for details.
5. “X” means “H or L” (but a dened logic level).
6. Self refresh exit is asynchronous.
