A read-write circuit has two data lines each of which is associated with a read circuit. The read circuit consists of three transistors connected in series, which operate in the low-signal mode in reading. By taking current from or into the bit lines according to the previously stored information the voltage ratios are changed at the outputs by which a data output driver is controlled. In writing, the n-transistors in the read circuits form with two p-transistors NOT circuits whose outputs form the data lines.
