PIN FUNCTION
CK0 Input Master Clock:All other inputs are referenced to the rising edge of CK Clock Enable:CKE controls internal clock.When CKE is low,internal clock for the following cycle is ceased. 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. Chip Select: When /S is high,any command means No Operation. Combination of /RAS,/CAS,/W defines basic commands. A0-11 specify the Row/Column Address in conjunction with BA.The Row Address is specified by A0-11.The Column Address is specified by A0-10.A10 is also used to indicate precharge option.When A10 is high at a read / write command, an auto precharge is performed. 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

BASIC FUNCTIONS
The MH64S72AWJA provides basic functions,bank(row)activate,burst read / write, bank(row)precharge,and auto / self refresh. 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 /RAS /CAS /WE CKE A10
Chip Select : L=select, H=deselect Command Command Command Ref resh Option @ref resh command 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.First 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] REFA command starts auto-refresh cycle. Refresh address including bank address are generated internally. After this command, the banks are precharged automatically.

POWER ON SEQUENCE
Before s tarting normal operation, the following power on sequence is necessary to prevent a SDRAM from damaged or malfunctioning. 1. Apply power and start clock. Attempt to maintain CKE high, DQMB0-7 high and NOP condition at the inputs. 2. Maintain stable power, stable clock, and NOP input conditions for a minimum of 200us. 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 register. After these sequence, the SDRAM is idle state and ready for normal operation.
MODE REGISTER
Burs t 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.
