Abstract
Official abstract text for this publication.
A refresh leveraging driving method is provided which includes deciding a unit of word lines to be driven at a refresh leveraging operation to be the same as a redundancy repair row unit setting a lower row address of an input refresh leveraging address corresponding to the decided refresh leveraging row driving unit to a don't care state; and internally generating the don't care lower row address of the refresh leveraging address to drive word lines according to a combined refresh leveraging address.
First claim
Opening claim text (preview).
What is claimed is: 1. A refresh leveraging driving method, comprising: setting, by a semiconductor device, a unit of word lines of a refresh leveraging row driving unit to have the same number of word lines as a number of word lines of a redundancy repair row unit; setting, by the semiconductor device, a lower row address of an input refresh leveraging address to a don't care state, the lower row address corresponding to the refresh leveraging row driving unit; and generating…
