256M Double Data Rate Synchronous DRAM
The DDR SDRAM has four independent banks. Each bank is activated by the ACT command with the bank
addresses (BA0,1). A row is indicated by the row address A12-0. The minimum activation interval between
banks is tRRD.
BANK ACTIVATE (ACT)
OPERATIONAL DESCRIPTION
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 all banks at the same time. After tRP from the
precharge, an ACT command to the same bank can be issued.
PRECHARGE (PRE)
Bank Activation and Precharge All (BL=8, CL=2)
A precharge command can be issued after BL/2 time from a read command.
