12、A10 are sampled during the ACTIVE 60 to 66command (row-address A0-A10) and READ/WRITE command (A0-A7 24with A10 defining auto precharge) to select one location out of the memory array in the respective bank. A10 is sampled during a PRECHARGE command to determine if all banks are to be precharged (A1
13、0 HIGH) or bank selected by BA0, BA1 (LOW). The address inputs also provide the op-code during a LOAD MODE REGISTER command. BA0, BA122,23Input PinBank Select Address: BA0 and BA1 defines which bank the ACTIVE, READ, WRITE or PRECHARGE command is being applied. CAS18Input PinCAS, in conjunction with
14、 the RAS and WE, forms the device command. See the Command Truth Table for details on device commands. CKE67Input PinThe CKE input determines whether the CLK input is enabled. The next rising edge of the CLK signal will be valid when is CKE HIGH and invalid when LOW. When CKE is LOW, the device will
15、 be in either power-down mode, clock suspend mode, or self refresh mode.CKE is an asynchronous input. CLK68Input PinCLK is the master clock input for this device. Except for CKE, all inputs to this device are acquired in synchronization with the rising edge of this pin. C S20Input PinThe CS input de
16、termines whether command input is enabled within the device. Command input is enabled when CS is LOW, and disabled with CS is HIGH. The device remains in the previous state when CS is HIGH.
