ABSTRACT:
A dual-port memory includes a plurality of memory cells coupled to a row decoder and column logic. Each memory cell includes two storage nodes, where each storage node is coupled to a bit line via an access transistor. Each memory cell also includes a logic gate for logically combining a word line signal with a column address signal and providing the resulting output signal to the gates of the access transistors. In one embodiment, the logic gate is a NOR logic gate and in another embodiment, the logic gate is a transmission gate. This prevents a potential read disturb problem with unselected memory cells of a row. This also reduces power consumption in the memory.
