256Mb (16-Meg X 4-Bit X 4-Banks) SDRAM
01.11.05 Rev 2
1. Different bank: When some banks are in the active state, the second write command (another bank) is
executed. However, DQM must be set High so that the output buffer becomes High-Z before data input. The
internal auto-precharge of one bank starts at the next clock of the second command.
Read with Auto Precharge to Write Command Interval (Different bank)
2. Same bank: The consecutive write command from read with auto precharge ( the same bank) is illegal. It
is necessary to separate the two commands with a bank active command.
Write with Auto Precharege to Read command interval
