Write command
(CS ,CAS ,
WE
= Low, RAS = High)
If the mode register is in the burst write mode, this command sets the burst start
address given by the column address to begin the burst write operation. The first
write data in burst can be input with this command with subsequent data on following
clocks.
Read command
(CS ,CAS = Low, RAS ,
WE
= High)
Read data is available afterCAS latency requirements have been met.
This command sets the burst start address given by the column address.
CBR (auto) refresh command
(CS ,RAS ,CAS = Low,
WE
, CKE = High)
This command is a request to begin the CBR refresh operation. The refresh
address is generated internally.
Before executing CBR refresh, all banks must be precharged.
After this cycle, all banks will be in the idle (precharged) state and ready for a
row activate command.
During t
RC
period (from refresh command to refresh or activate command), the
M12L128168A cannot accept any other command.
