DESCRIPTION
CK0~CK3
Clock Inputs
The system clock input. All other inputs are registered to the SDRAM on the
rising edge of CLK
CKE0
Clock Enable
Controls internal clock signal and when deactivated, the SDRAM will be one
of the states among power down, suspend or self refresh
/S0, /S2
Chip Select
Enables or disables all inputs except CK, CKE and DQM
BA0, BA1
SDRAM Bank Address
Selects bank to be activated during /RAS activity
Selects bank to be read/written during /CAS activity
A0 ~ A11
Address
Row Address : RA0 ~ RA11, Column Address : CA0 ~ CA9
Auto-precharge flag : A10
/RAS, /CAS, /WE
Row Address Strobe, Column
Address Strobe, Write Enable
/RAS, /CAS and /WE define the operation
