MRD
The DRAM has a mode register that defines how the device operates. In this
The mode register can be set only when all banks are in idle state. During 2CLK
The DRAM has an extended mode register that defines how to set PASR, DS.
The DRAM has four banks, each with 4,096 rows.
This command activates the bank selected by BA1 and BA0 (BS) and a row
This command corresponds to a conventional DRAM’s RAS falling.
) following this command, the DRAM cannot accept any other commands.
