Selects bank to be activated during RAS activity
Selects bank to be read/written during CAS activity
Multiplexed data input / output pin
The system clock input.All other inputs are registered to the SDRAM
on the rising edge of CLK
Controls internal clock signal and when deactivated,the SDRAM will
be one of the states among power down,suspend or self refresh
Enables or disables all inputs except CLK, CKE and DQM
RAS,CAS and WE define the operation
Refer function truth table for details
Controls output buffers in read mode and masks input data in write
mode
Power supply for internal circuits and input buffers
Power supply for output buffers
