Abstract
A dynamic random access memory device having an input/output load connected between a pair of input/output lines and a control circuit used to generate an internal /RAS signal having a reset transition delayed with respect to the same transition of the external /RAS signal. The internal /RAS signal controls at least a word signal applied to a transistor of a selected memory cell and an enable signal applied to an enable transistor, whereby the time the transistor of the memory cell and the enable transistor become non-conductive is delayed with respect to the time at which a transfer transistor connected between each pair of bit lines and the input/output lines becomes non-conductive.
