BASIC FUNCTIONS
The MH28S72PJG 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.
/S
Chip Select : L=select, H=deselect
/RAS

/CAS

/WE

CK
define basic commands
Activate(ACT) [/RAS =L, /CAS = /WE =H]
Read(READ) [/RAS =H,/CAS =L, /WE =H]
Write(WRITE) [/RAS =H, /CAS = /WE =L]
Precharge(PRE) [/RAS =L, /CAS =H,/WE =L]
Auto-Refresh(REFA) [/RAS =/CAS =L, /WE =CKE =H]
ACT command activates a row in an idle bank indicated by BA.
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 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
).
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
).
REFA command starts auto-refresh cycle. Refresh address including bank address
are generated internally. After this command, the banks are precharged automatically.
