... MCD command execution. Active Command (CS, RAS = LOW, CAS, WE= HIGH) The IC42S16100 includes two banks of 4096 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 ...

... IC42S16100 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 ...

... IC42S16100 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.
