Semiconductor memory device

Abstract

A semiconductor memory device includes a plurality of bit lines disposed over memory cells along a second direction intersecting with a first direction, and extending in the first direction; and a plurality of s first wirings and a plurality of second wirings alternately disposed along the second direction over the bit lines, and extending in the first direction while being bent into zigzag shapes.

Description

CROSS-REFERENCE TO RELATED APPLICATION[0001]The present application claims priority under 35 U.S.C. § 119(a) to Korean Patent Application No. 10-2018-0095331, filed on Aug. 16, 2018, which is incorporated herein by reference in its entirety.BACKGROUND1. Technical Field[0002]Various embodiments of the present invention generally relate to a semiconductor memory device and, more particularly, to a semiconductor memory device having improved wiring structure that allows enhanced integration, and performance and lower power consumption.2. Related Art[0003]In recent years, memory devices trend toward larger capacity and higher degree of integration in step with increased multifunctionality and capacity of the information communication devices employing the memory devices. As the size of the memory cells shrinks for obtaining higher integration, the structure of operation circuits and wirings which are included in a memory device for the operation and electrical coupling of the memory dev...

AI Technical Summary

Benefits of technology

This patent is about a new semiconductor memory device that has a better way to connect the wires, making it possible to put more memory cells in the device and use less power. This will make the device perform better and be more reliable.

Problems solved by technology

As the size of the memory cells shrinks for obtaining higher integration, the structure of operation circuits and wirings which are included in a memory device for the operation and electrical coupling of the memory device becomes more complex and a potential bottleneck in the efforts to improve the memory devices.
