Commands – Truth Tables
2. RESET# is enabled LOW and used only for asynchronous reset. Thus, RESET# must be
held HIGH during any normal operation.
3. The state of ODT does not affect the states described in this table.
4. Operations apply to the bank defined by the bank address. For MRS, BA selects one of
four mode registers.
5. “V” means “H” or “L” (a defined logic level), and “X” means “Don’t Care.”
6. See Table 71 (page 115) for additional information on CKE transition.
7. Self refresh exit is asynchronous.
8. Burst READs or WRITEs cannot be terminated or interrupted. MRS (fixed) and OTF BL/BC
are defined in MR0.
9. The purpose of the NOP command is to prevent the DRAM from registering any unwan-
ted commands. A NOP will not terminate an operation that is executing.
10. The DES and NOP commands perform similarly.
11. The power-down mode does not perform any REFRESH operations.
12. ZQ CALIBRATION LONG is used for either ZQinit (first ZQCL command during initializa-
tion) or ZQoper (ZQCL command after initialization).
