The present invention relates to a block selection circuit of a flash memory device. The block selection circuit includes a control signal output unit, switching means, and an operation controller. The control signal output unit outputs a control signal for enabling or disabling memory blocks connected thereto by employing block address signals. The block address signals are decoded according to an input address and provided. The switching means switches the control signal so that the control signal is input as a block selection control signal. The operation controller turns off drain and source select transistors of a memory block connected thereto according to a logic level of a first control signal.
