ABSTRACT:
A method for controlling a word line signal for a memory device during a power down process, comprising: pulling the word line signal down to a low logic state; disconnecting a current path from an external power supply to an internal power supply after the word line signal has been pulled down to the low logic state; and disconnecting a current path from an external ground voltage to an internal ground voltage after a current path from an external power supply to an internal power supply has been completely disconnected.
