ABSTRACT:
A semiconductor memory device has a device for reading stored information out of a memory element of a semiconductor by applying a reading voltage onto a word line; and a single word line clamping circuit for controlling the reading voltage applied onto the word line such that the reading voltage is close to a relatively high threshold voltage of the memory element when the reading voltage is applied onto the word line, the word line clamping circuit being commonly disposed on a plurality of word lines.
