... Active Command (CS, RAS = LOW, CAS, WE= HIGH) The IS42S16100 includes two banks of 2048 rows each. This command selects one of the two banks according to the A11 pin and activates the row selected by the pins A0 to A10. This command corresponds to the fall of the RAS signal from HIGH to LOW in conventional DRAMs ...

... IS42S16100 Self-Refresh Command (CS, RAS, CAS, CKE = LOW HIGH) This command executes the self-refresh operation. The row address to be refreshed, the bank, and the refresh interval are generated automatically internally during this operation. The self-refresh operation is started by dropping the CKE pin from HIGH to LOW. The self-refresh operation continues as long as the CKE pin remains LOW and there is no need for external control of any other pins ...

... IS42S16100 Burst Read The read cycle is started by executing the read command. The address provided during read command execution is used as the starting address.

... IS42S16100 Interval Between Write and Read Commands A new read command can be executed while a write cycle is in progress, i.e., before that cycle completes.

... CAS latency, as soon as one of the U/LDQM pins goes HIGH, the corresponding externally applied input data will no longer be written to the device internal circuits. Subsequently, the corresponding input continues to be muted as long as that U/LDQM pin remains HIGH. The IS42S16100 will revert to accepting input as soon as CLK COMMAND UDQM ...

... CAS latency = 3 Clock Suspend When the CKE pin is dropped from HIGH to LOW during a read or write cycle, the IS42S16100 enters clock suspend mode on the next CLK rising edge.
