发明名称 Dual port memory device
摘要 A multi-port memory device having a storage node, a precharge node, a first, second, third, and fourth transistor, and a control module. The first transistor includes a current electrode connected to the storage node, another current electrode connected to a first bit line, and a gate connected to a first wordline. The second transistor includes a current electrode connected to the storage node, another current electrode connected to a second bit line, and a gate connected to a second wordline. The third transistor includes a current electrode connected to the reference node, another current electrode connected to the first bit line, and a gate. The fourth transistor includes a current electrode connected to the precharge node, another current electrode connected to the second bit line, and a gate. The control module deactivates the fourth transistor in response to a dummy access of the first storage module at the second transistor.
