Abstract: A method and device for setting at lease three operating modes of a memory device is provided. The voltage signal is sensed at a first input and an enable signal is sensed at a second input. When an enable signal is received at a second input the memory device operates at the first operating mode if the voltage state at the first input is low; it operates at a second mode if the voltage state at the second is high; and it operates at a third operating mode if the voltage at the first input changes after the enable signal is received at the input. Also a four mode operation can be achieved.
