After self refresh mode started, becomes asynchronous input.Self refresh maintained long low. Chip Select: When high,any command means Operation. Combination /RAS,/CAS,/WE defines basic commands. A0-10 specify Row/Column Address conjunction with BA.The Address specified A0-10.The Column Address specified A0-7.A10 also used indicate precharge option.When high read write command, auto precharge performed. When high precharge command, both banks precharged.
