    摘要: A reference voltage generation circuit is provided which includes a p-channel type MOSFET used as an input transistor to allow a sufficient current to flow through a differential amplifier even if the threshold voltages of MOSFETs used in the differential amplifier significantly increase. A push-pull conversion circuit is coupled to the differential amplifier and has a double end configuration to provide a sufficiently high level to drive a p-channel output buffer. This arrangement allows a stable operation at a sufficiently low power supply voltage even if the threshold voltages of the MOSFETs forming the differential amplifier are high. It also allows quick activation when the power is turned on and provides high stability.

    摘要: A direct sense amplifier of the present invention incorporates and isolates: an MOS transistor serving as a differential pair and having a gate connected to a bit line; and an MOS transistor controlled by a column select line wired between RLIO lines in a bit-line direction, and further connects a source of the MOS transistor serving as the differential pair to a common source line wired in the word-line direction. Since the direct sense amplifier only in a select map is activated by the column select line and the common source line during an read operation, power consumption is significantly reduced during the read operation. Also, since a parasitic capacitance of the MOS transistor serving as the differential pair is separated from the local IO line, a load capacity of the local IO line is reduced and the read operation is speeded up. In addition, during the read operation, a data pattern dependency of the load capacity of the local IO line is reduced and a post-manufacture test is easily made.

    摘要: The contact resistance of each switch is reduced, and the on-resistances of all of the switches are set to be uniform, while the area required for arrangement of bit line selection switches is not increased.The switches are connected to one-side ends of the bit lines provided at the odd-numbered positions, and are connected to the other-side ends of the bit lines provided at the even-numbered positions. A pair of odd-numbered or even-numbered bit lines are connected to the terminals of each sense amplifier, respectively. The memory cells are arranged at predetermined intersection points of the word lies and the bit lines, the number of the predetermined intersection points being equal to half of all the intersection points thereof, in such a manner that when one word line is selected, the memory cells connected to the selected word-line can be electrically connected in such a manner that one memory cell is electrically connected to each terminal of the unit circuits.
