SEMICONDUCTOR MEMORY APPARATUS HAVING A SUB-WORD LINE DRIVER FOR INCREASING AN AREA MARGIN IN THE MEMORY CORE AREA
First Claim
1. A semiconductor memory apparatus comprising:
- a sub-word line driver configured to operate in response to an activation of a main word line and in response to positive and negative sub-word line enable signals,wherein the sub-word line driver includes;
a pull-up driver configured to pull-up drive a first sub-word line to a potential level of the positive sub-word line enable signal in response to the activation of the main word line; and
a pull-down driver configured to pull-down drive the first sub-word line in response to the negative sub-word line enable signal.

Abstract
A semiconductor memory apparatus with a sub-word line driver is presented which has an increased area margin in the memory core area. The sub-word line driver is configured to operate in response to activation of a main word line and in response to positive and negative sub-word line enable signals. The sub-word line driver includes a pull-up driver and a pull-down driver. The pull-up driver is configured to pull-up drive a first sub-word line to the potential level of the positive sub-word line enable signal in response to the activation of the main word line. The pull-down driver is configured to pull-down drive the first sub-word line in response to the negative sub-word line enable signal.
