7.4. Active
Before any READ or WRITE commands can be issued to a bank in the LPDDR SDRAM, a row in that bank must be
opened. This is accomplished by the ACTIVE command: BA0 and BA1 select the bank, and the address inputs
select the row to be activated. More than one bank can be active at any time.
Once a row is open, a READ or WRITE command could be issued to that row, subject to the t RCD specification.
A subsequent ACTIVE command to another row in the same bank can only be issued after the previous row has
been closed. The minimum time interval between two successive ACTIVE commands on the same bank is defined
by t RC .
