BASIC FUNCTIONS
The MH64D72KLG 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 CLK rising edge. In addition to 3 signals, /CS ,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.

define 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, all banks are deactivated
(precharge all,
PREA
).
Auto-Refresh (REFA) [/RAS =/CAS =L, /WE =CKE0 =H]
REFA command starts auto-refresh cycle. Refresh address including bank address are
generated internally. After this command, the banks are precharged automatically.
