    摘要: In an operation of transferring data between a DRAM array and an SRAM array through a bidirectional transfer gate circuit, data blocks on a selected one in the DRAM array are sequentially selected in a high speed mode, word lines are sequentially selected in the SRAM array, so that data is transferred in a time division multiplexing manner between the DRAM array and the SRAM array in units of data block. A cache block size in a semiconductor memory device containing a cache can be externally changed depending on the application with the internal configuration maintained unchangedly.

    摘要: 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.

    摘要: A substrate bias potential generator for biasing a semiconductor substrate to a predetermined potential includes first and second substrate bias generating circuits which operate alternatively according to the potential of the substrate, whereby consumption of power in the substrate bias potential generator is reduced. The alternative operation of the bias generating circuits each activated by a pulse signal train is performed by using a first insulated gate transistor having a gate electrode connected to the semiconductor substrate, a second insulated gate transistor having a gate electrode for receiving the reference potential, an amplifier for differentially amplifying outputs of the first and second insulated gate transistors, an insulated gate transistor for charging an output of the amplifier to a predetermined potential when the amplifier is activated, and a circuit for transmitting the output of the differential amplifier to the first and second bias potential generating circuits. The differential amplifier is activated in response to an activation signal of a pulse train whereby an activation signal corresponding to the pulse train is transmitted to either substrate bias potential generating circuit.
