OPERATIONAL DESCRIPTION
Bank Activate
The SDRAM has two independent banks. Each bank is activated by
the ACT command with the bank address (BA). A row is indicated
by the row address A[10:0] The minimum activation interval
between one bank and the other bank is t_RRD.
Precharge
The PRE command deactivates the bank indicated by BA. When
both banks are active, the precharge all command (PREA, PRE +
A[10] = H) is available to deactivate them at the same time. After
t_RP from the precharge, an ACT command can be issued.
