ABSTRACT:
A circuit for generating a switching control signal which is capable of selectively connecting an internal voltage in the read mode with respect to the driving voltage of a driver and connecting an external voltage in the write mode. The circuit includes a Y-decoder for decoding a Y-address, a Y-driver driven by an internal voltage or an external voltage for outputting a switching control signal, a first switching means controlled by a read enabling bar signal and applying or blocking the internal voltage to/from the Y-driver, and a second switching means controlled by the write enabling signal for applying or blocking the external voltage to/from the Y-driver.
