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.

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.

Before starting 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.
Burst Length, Burst Type and /CAS Latency can be programmed by setting the mode
register(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.
