OPERATION COMMAND TABLE
Current State Command
Notes:
1. H: HIGH level input, L: LOW level input, X: HIGH or LOW level input, V: Valid data input
2. All input signals are latched on the rising edge of the CLK signal.
3. Both banks must be placed in the inactive (idle) state in advance.
4. The state of the A0 to A11 pins is loaded into the mode register as an OP code.
5. The row address is generated automatically internally at this time. The DQ pin and the address pin data is ignored.
6. During a self-refresh operation, all pin data (states) other than CKE is ignored.
7. The selected bank must be placed in the inactive (idle) state in advance.
8. The selected bank must be placed in the active state in advance.
9. This command is valid only when the burst length set to full page.
10. This is possible depending on the state of the bank selected by the A11 pin.
11. Time to switch internal busses is required.
12. The IS42S16100C1 can be switched to power-down mode by dropping the CKE pin LOW when both banks in the idle
state. Input pins other than CKE are ignored at this time.
13. The IS42S16100C1 can be switched to self-refresh mode by dropping the CKE pin LOW when both banks in the idle state.
Input pins other than CKE are ignored at this time.
14. Possible if t
15. Illegal if t
16. The conditions for burst interruption must be observed. Also note that the IS42S16100C1 will enter the precharged state
immediately after the burst operation completes if auto-precharge is selected.
17. Command input becomes possible after the period t
precharged state immediately after the burst operation completes if auto-precharge is selected.
18. A8,A9 = don’t care.
