CKE is also used to select auto / self refresh. After self refresh mode is started, CKE E becomes asynchronous input.Self refresh is maintained as long as CKE is low. /S0 - 3 Input Chip Select: When /S is high,any command means No Operation. /RAS,/CAS,/W Input Combination of /RAS,/CAS,/W defines basic commands.

When A10 is high at a precharge command, both banks are precharged. Bank Address:BA0,1 is not simply BA.BA0,1 specifies the bank to which a command is applied.BA must be set with ACT,PRE,READ,WRITE commands Input/Output Data In and Data out are referenced to the rising edge of CK Input Din Mask/Output Disable:When DQMB is high in burst write.Din for the current cycle is masked.When DQMB is high in burst read,Dout is disabled at the next but one cycle. Power Supply Power Supply for the memory mounted module. Output Register enable:When REGE is low,All control signals and address are buffered. (Buffer mode) When REGE is high,All control and address are latched.

Each command is defined by control signals of /RAS,/CAS and /WE at CK rising edge. In addition to 3 signals,/S,CKE and A10 are used as chip select,refresh option,and precharge option,respectively. To know the detailed definition of commands please see the command truth table. CK /S Chip Select : L=select, H=deselect /RAS Command /CAS Command /WE Command CKE Ref resh Option @ref resh command A10 Precharge Option @precharge or read/write command def ine basic commands Activate(ACT) [/RAS =L, /CAS = /WE =H] ACT command activates a row in an idle bank indicated by BA. Read(READ) [/RAS =H,/CAS =L, /WE =H] READ command starts burst read from the active bank indicated by BA.Firs t output data appears after /CAS latency. When A10 =H at this command,the bank is deactivated after the burst read(auto-precharge,READA). Write(WRITE) [/RAS =H, /CAS = /WE =L] WRITE command starts burst write to the active bank indicated by BA. Total data length to be written is set by burst length. When A10 =H at this command, the bank is deactivated after the burst write(auto-precharge,WRITEA). Precharge(PRE) [/RAS =L, /CAS =H,/WE =L] PRE command deactivates the active bank indicated by BA. This command also terminates burst read / write operation. When A10 =H at this command, both banks are deactivated(precharge all, PREA). Auto-Refresh(REFA) [/RAS =/CAS =L, /WE =CKE =H] PEFA command starts auto-refresh cycle. Refresh address including bank address are generated internally. After this command, the banks are precharged automatically.

Apply power and start clock. Attempt to maintain CKE high, DQMB high and NOP condition at the inputs. 2. Maintain stable power, stable cock, and NOP input conditions for a minimum of 200µs. 3. Issue precharge commands for all banks. (PRE or PREA) 4. After all banks become idle state (after tRP), issue 8 or more auto-refresh commands. 5. Issue a mode register set command to initialize the mode regis ter. After these sequence, the SDRAM is idle state and ready for normal operation. MODE REGISTER Burst Length, Burst Type and /CAS Latency can be programmed by setting the mode regis ter(MRS). The mode register stores these date until the next MRS command, which may be issue when both banks are in idle state. After tRSC from a MRS command, the SDRAM is ready for new command.
