In a MIS random access memory device including a data-in amplifier and MIS memory cells, a device is provided for holding the output level of the data-in amplifier at the precharge potential of the memory cells except during a write operation by controlling an input circuit and a driver circuit of the data-in amplifier through utilizing the read/write signal and the control signal for the memory. Data stored in the memory cells are free from the influence of the output of the data-in amplifier during a non-write operation.
