FUNCTIONAL BLOCK DIAGRAM 
PIN FUNCTION DESCRIPTION 
PIN  NAME  INPUT FUNCTION 
  CLK    System Clock    Active on the positive going edge to sample all inputs 
  CS  
  Chip Select 
  Disables or enables device operation by masking or enabling all 
  inputs except CLK , CKE and L(U)DQM 
 CKE   Clock Enable 
  Masks system clock to freeze operation from the next clock cycle. 
  CKE should be enabled at least one cycle prior new command. 
  Disable input buffers for power down in standby. 
  A0 ~ A11    Address 
  Row / column address are multiplexed on the same pins. 
  Row address : RA0~RA11, column address : CA0~CA7 
  BA1 , BA0    Bank Select Address 
  Selects bank to be activated during row address latch time. 
  Selects bank for read / write during column address latch time. 
  RAS  
  Row Address Strobe 
  Latches row addresses on the positive going edge of the CLK with 
  RAS  low. 
  Enables row access & precharge. 
  CAS  
  Column Address Strobe 
  Latches column address on the positive going edge of the CLK with
  CAS  low. 
  Enables column access. 
 
WE  
  Write Enable 
  Enables write operation and row precharge. 
  Latches data in starting from  CAS , 
WE  active. 
  L(U)DQM    Data Input / Output Mask 
  Makes data output Hi-Z, t
SHZ after the clock and masks the output. 
  Blocks data input when L(U)DQM active. 
  DQ0 ~ DQ15    Data Input / Output    Data inputs / outputs are multiplexed on the same pins. 
  VDD / VSS    Power Supply / Ground    Power and ground for the input buffers and the core logic. 
  VDDQ / VSSQ    Data Output Power / Ground 
  Isolated power supply and ground for the output buffers to provide   
  improved noise immunity.   
  NC    No Connection    This pin is recommended to be left No Connection on the device.
