The NO OPERATION (NOP) command is used to perform a NOP to the selected device
(CS# is LOW). This prevents unwanted commands from being registered during idle or
wait states. Operations already in progress are not affected.
The mode registers are loaded via inputs A[n:0] (where An is the most significant ad-
dress term), BA0, and BA1(see Mode Register (page 46)). The LOAD MODE REGISTER
command can only be issued when all banks are idle and a subsequent executable com-
mand cannot be issued until
The ACTIVE command is used to activate a row in a particular bank for a subsequent
access. The value on the BA0, BA1 inputs selects the bank, and the address provided
selects the row. This row remains active for accesses until a PRECHARGE command is
issued to that bank. A PRECHARGE command must be issued before opening a differ-
ent row in the same bank.
