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 tRRD.
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
tRP from the precharge, an ACT command can be issued.
