    摘要: A nonvolatile semiconductor memory device comprising a power source terminal and a P-channel MOS transistor. A low power-source voltage is applied to the terminal during a read period. The source of the P-channel MOS transistor is coupled to the power source terminal. The conduction of the MOS transistor is controlled by data-writing operation. The drain of the MOS transistor is connected by a node to a plurality of bit lines. The device further comprises a plurality of memory cells and a plurality of N-channel MOS transistor. The memory cells have double-gate structure, each having a source coupled to the ground and a drain coupled to the corresponding bit line. Each N-channel MOS transistor has a source and a drain connected to the ground and the corresponding bit line, respectively, for discharging the bit line. Each N-channel MOS transistor is rendered conductive temporarily when the supply of the high power source voltage to the power source terminal is started, whereby the potential of the corresponding bit line is decreased. The bit-line potential is decreased sufficiently since the P-channel MOS transistors have a conductance greater than that of any other transistor incorporated in the device.

    摘要: A chain type ferroelectric random access memory has a memory cell unit including ferroelectric memory cells electrically connected in series to each other, a plate line connected to an electrode of the memory cell unit, a bit line connected to the other electrode of the memory cell unit via a switching transistor, a sense amplifier which amplifies the voltages of this bit line and its complementary bit line, and a transistor inserted between the switching transistor and the sense amplifier. A value, being the minimum value of the gate voltage in the transistor obtained during elevation of the plate line voltage and comparative amplification, is smaller than a value, being the maximum value of the gate voltage in the transistor obtained during fall of the plate line voltage and comparative amplification. With these features, decrease in the accumulated charge of polarization in the memory cell is reduced and occurrence of disturb is prevented during read/write operations.

    摘要: A variable potential generating circuit includes a resistive potential divider circuit and first and second operational amplifiers. The resistive potential divider circuit includes a switching element and a current-scaling type digital/analog converter circuit connected in series between a power supply node and a ground node. The resistive potential divider circuit has a first node at which a divided potential obtained by resistive division of a variable potential to be output from a variable potential output node appears and a second node to which a virtual potential is applied. The first operational amplifier compares the divided potential of the first node with a reference potential to effect the feedback control for setting the variable output potential equal to the reference potential. The second operational amplifier compares the virtual potential of the second node with the reference potential to effect the feedback control for setting the virtual potential equal to the reference potential.
