Notes:
Table 18: DM Operation Truth Table
The DESELECT function (CS# HIGH) prevents new commands from being executed by
the device. Operations already in progress are not affected.
The NO OPERATION (NOP) command is used to instruct the selected device to perform
a NOP. 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[0:n]. See mode register descriptions in Stand-
ard Mode Register (page 56) and Extended Mode Register (page 60). The LOAD
MODE REGISTER command can only be issued when all banks are idle, and a subse-
quent executable command cannot be issued until
The ACTIVE command is used to activate a row in a particular bank for a subsequent
access. The values on the BA0 and BA1 inputs select the bank, and the address provided
on inputs A[0:n] selects the row. This row remains active for accesses until a PRE-
CHARGE command is issued to that bank. A PRECHARGE command must be issued
before opening a different row in the same bank.
