APPARATUS FOR DRIVING SUB WORDLINE

摘要

PURPOSE: An apparatus for driving a sub wordline is provided to reduce a layout area by using a low voltage NMOS transistor for a driver, to improve driving capability and speed and to increase the reliability of access timing. CONSTITUTION: An apparatus for driving a sub wordline is composed of a low voltage NMOS(LN) and an NMOS transistor(MN). A main wordline driving signal(MWL) and a sub wordline decoding signal are supplied to the gate and drain of the low voltage NMOS(LN) respectively. A main wordline driving signal(MWLB) is supplied to the gate of the NMOS transistor(MN). The source of the NMOS transistor(MN) is grounded. The drain of the NMOS transistor(MN) outputs a sub wordline driving signal(SWL) in common with the source of the low voltage NMOS(LN).
