Semiconductor memory device with burst mode access

摘要

A data sensing control circuit according to the present invention is provided in a semiconductor memory device with a burst access mode. The data sensing control circuit generates sensing control signals for data sensing operation by use of a transition information of an address bit signal synchronized with a read enable clock signal and used for a bank selection. According to such a data sensing control scheme, no sensing of each sensing period is performed when the read enable clock signal transitions. Therefore, a power noise (or input/output noise) issued at data-out does not affect the data sensing operation of the semiconductor memory device having the burst access mode.
