ABSTRACT:
A semiconductor memory includes a plurality of semiconductor memory cells and a first select line for providing a first select signal to access a selected memory cell, a second select line for providing a second select signal to access a selected memory cell, the first and second select signals being independent, a first transmission line for coupling an information with the memory cell synchronizing to the first signal and a second transmission line for coupling an information with the memory cell synchronizing to the second signal. Each memory cell includes a storage element for storing an information, with at least one input-output terminal and at least one input-output section. The section includes a first input-output control element with a control electrode connected to the first select line, a first input-output electrode connected to the input-output terminal of the storage element, and a second input-output electrode connected to the first transmission line, the first control element transmitting signals between the first and the second input-output electrode when the control electrode is activated with the first select signal, and a second input-output control element with a control electrode connected to the second select line, a first input-output electrode connected to the input output terminal of the storage element, and a second input-output electrode connected to the second transmission line, the second input-output control element transmitting signals between the first and second input-output electrode when the control electrode is activated with the second select signal.
