DESCRIPTION
INPUT
Clock : The system clock input. All other inputs are registered to the SDRAM on the
rising edge of CLK
INPUT
Clock Enable : Controls internal clock signal and when deactivated, the SDRAM will
be one of the states among power down, suspend or self refresh
INPUT Chip Select : Enables or disables all inputs except CLK, CKE, DQM0~DQM3
INPUT
Bank Address : Selects bank to be activated during RAS activity
Selects bank to be read/written during CAS activity
INPUT
Row Address : RA0 ~ RA12, Column Address : CA0 ~ CA8
Auto-precharge flag : A10
INPUT
Command Inputs : RAS, CAS and WE define the operation
Refer function truth table for details
INPUT
Data Mask:Controls output buffers in read mode and masks input data in write
mode
I/O
Data Input/Output:Multiplexed data input/output pin
SUPPLY Power supply for internal circuits
SUPPLY Power supply for output buffers
