    • A dynamic random access memory with self-refresh function, which includes a substrate bias generator (100) adapted to be intermittently driven to apply a bias potential to a semiconductor substrate (15). This memory device comprises a circuit (91) for generating an internal refresh instruction signal (.phi..sub.S) in response to an external refresh instruction signal, a circuit (92, 93) which, in response to the internal refresh instruction signal, generates a refresh enable signal (.phi..sub.R) intermittently at a predetermined interval, a circuit (94, 95, 96, 98) which, in response to the refresh enable signal, refreshes data in the memory cells, and a circuit (99) which, in response to the internal refresh instruction signal and refresh enable signal, activates the substrate bias generator in the same cycle as the cycle of generation of the refresh enable signal and only for a time shorter than the cycle of generation of the refresh enable signal. The above construction contributes to a reduced power consumption in the dynamic random access memory.

    • A dynamic-type semiconductor memory device has a test mode of simultaneously carrying out functional testing on a plurality of bits of memory cells. In data writing in the test mode, data inverted from the write-in data is written in at least a 1-bit memory cell out of the plurality of bits of memory cells selected simultaneously, and the same data as the write-in data is written in the remaining memory cells. In data reading in the test mode, the data of those of the memory cells selected simultaneously, in which the inverted data is written are inverted and read, while the data of the remaining memory cells are read as they are. Logic processing is carried out on the read-out data of the plurality of bits, so that a logic value indicating acceptability of the semiconductor memory device is output, depending on a result of determination as to whether or not the read-out data is the same as each other.
