OPERATIONAL DESCRIPTION
BANK ACTIVATE
The DDR SDRAM has four indep endent banks. Each bank is activated by the ACT command
with the bank addresses (BA0,1). A row is indicated by the row address A11-0. The minimum
activation interval between one bank and the other bank is tRRD. M aximum 2 ACT commands
are allowed within tRC,although the number of banks which are active concurrently is not limited.
PRECHARGE
The PRE command deactivates the bank indicated by BA0,1. When multiple banks are active,
the precharge all command (PREA,PRE+A10=H) is available to deactivate them at the same
time. After tRP from the precharge, an ACT command to the same bank can be issued.
A precharge command can be issued at BL/2(Discrete) from a read command without data loss.
