ABSTRACT:
A wordline driver for use with a SDRAM of a semiconductor device is provided. The wordline driver can be used for a global wordline driver suitable for a merged bank architecture (MBA). The wordline driver can include a set unit for setting a wordline driver by receiving coding signals coded in an X-address predecoder. A reset unit resets the wordline driver in accordance with a reset signal controlled by a precharge command and a first coding signal. A drive unit enables/disables a wordline in accordance with operations of the set and reset units, and a latch unit latches an enabled/disabled state of the wordline. The coding signal can include upper, intermediate and lower coding signals based on a multi-bit X-address. Accordingly, the present invention is effective for the MBA in which the X-address predecoder is shared by providing a latch in a global wordline itself and latching an enabled/disabled state of the global wordline.
