    摘要: In a semiconductor memory device having a plurality of memory cells in which each memory cell is formed of an address selection MOSFET and an information storing capacitor and the plate voltage consisting of an intermediate potential is supplied to the common electrode of the information storing capacitor, the memory access is enabled by indirectly detecting that the plate voltage has reached a predetermined potential near a intermediate potential with the voltage detecting circuit or timer circuit, inhibiting the selecting operation of the word lines or precharging of the pair of bit lines to the intermediate potential when the plate voltage is lower than the predetermined potential, and then canceling the above inhibit condition after the plate voltage has reached the predetermined potential.

    摘要: In a dynamic RAM having a memory cell array in which a dynamic memory cell is arranged at an intersection between a word line and one of a pair of bit lines, a select level signal corresponding to a supply voltage and an unselect level signal corresponding to a negative potential lower than circuit ground potential are supplied to the word line. A signal of a memory cell read to the pair of bit lines by a sense amplifier that operates on the circuit ground potential and an internal voltage formed by dropping the supply voltage by an amount equivalent to the threshold voltage of the address select MOSFET is amplified. The dynamic RAM has an oscillator that receives the supply voltage and circuit ground potential and a circuit that receives an oscillation pulse generated by the oscillator to generate the negative potential.
