Abstract

Official abstract text for this publication.

A semiconductor memory device includes a semiconductor die and an input-output bump pad part. The semiconductor die includes a plurality of memory cell arrays. The input-output bump pad part is formed in a central region of the semiconductor die. The input-output bump pad part provides a plurality of channels for connecting each of the memory cell arrays independently to an external device. The semiconductor memory device may adopt the multi-channel interface, thereby having high performance with relatively low power consumption.

First claim

Opening claim text (preview).

What is claimed is: 1. A semiconductor memory device comprising: a plurality of semiconductor dies that are stacked, each semiconductor die including a plurality of memory cell arrays; and a plurality of input-output bump pad parts respectively located at a central region of each semiconductor die, the input-output bump pad parts providing a plurality of channels each dedicated to only a respective one of the memory cell arrays and by which each of the memory cell arrays can be…
