    • Negative characteristic MISFETs, which are of the same channel conductivity type and which have different threshold voltages, are formed in a doped silicon thin film deposited over a substrate and are connected in channel-to-channel series with each other. The pair of series-connected negative characteristic MISFETs, a resistive element, an information storage capacitive element and a transfer MISFET constitute an SRAM memory cell. Equivalently, a negative characteristic MISFET having a current-voltage characteristic defined by a negative resistance curve can be used in lieu of the pair of series-connected negative characteristic MISFETs in the formation of the individual memory cells of the SRAM. The negative resistance curve of the negative characteristic MISFET is shaped such that the linear current-voltage characteristic curve corresponding to the resistive element of the memory cell intersects the negative resistance curve at at least three location points. The negative characteristic MISFET, like the pair of series-connected negative characteristic MISFETs, has an active region formed in a doped thin film silicon (polycrystalline silicon) layer insulatedly above a substrate main surface. The resistive element is also formed in a thin film silicon layer either integrally with the negative characteristic MISFET or in a separate thin film silicon layer and in series electrical connection with the negative characteristic MISFET.
    • 具有相同沟道导电类型且具有不同阈值电压的负特性MISFET形成在沉积在衬底上并以通道间通道串联连接的掺杂硅薄膜中。 一对串联负特性MISFET,电阻元件,信息存储电容元件和转移MISFET构成SRAM存储单元。 等效地,可以使用由负电阻曲线限定的电流 - 电压特性的负特性MISFET来代替在SRAM的各个存储单元的形成中的一对串联负特性MISFET。 负特性MISFET的负电阻曲线被成形为使得对应于存储单元的电阻元件的线性电流 - 电压特性曲线在至少三个位置点处与负电阻曲线相交。 负极特性MISFET,像一对串联连接的负特性MISFET一样,具有在衬底主表面上绝缘的掺杂薄膜硅(多晶硅)层中形成的有源区。 电阻元件也与负特性MISFET或单独的薄膜硅层整体地形成在薄膜硅层中,并与负特性MISFET串联电连接。

    • In case an address is to access a defective memory cell, a defective memory cell in a memory cell area contained in one of paired memory mats is selected in parallel with a redundant memory cell in a redundant memory cell area contained in the other memory mat. At this time of selecting the redundant main word line for selecting the redundant memory cell, there is not required the logical operation for deciding whether or not the redundant use of the access address fed from the outside is proper. For example, the redundant main word line is set to the select level on the basis of a chip select signal. As a result, the drive start timing of the redundant main word line is not delayed in the least from the drive start timing of the main word line. Thus, it is possible to prevent the event that the select drive timing of the redundant sub word line is delayed on account of the delay in the drive timing of the redundant main word line.
    • 在地址要访问有缺陷的存储单元的情况下,在包含在其中一个存储器堆中的存储单元区域中的有缺陷的存储器单元与冗余存储器单元并联地选择在另一存储器堆中所包含的冗余存储单元区域中。 在选择用于选择冗余存储单元的冗余主字线时,不需要用于判断从外部馈送的访问地址的冗余使用是否合适的逻辑操作。 例如,基于片选信号将冗余主字线设定为选择电平。 结果,冗余主字线的驱动开始定时至少不会从主字线的驱动开始定时延迟。 因此,可以防止由于冗余主字线的驱动定时的延迟而使冗余子字线的选择驱动定时被延迟的事件。

    • A disk playback apparatus comprises a stocker including a plurality of shelves for compact disks, a pallet disposed adjacent to the stocker, a lift stage for moving the stocker up and down so that a selected one of the shelves is located in a position higher than the pallet for a predetermined distance, a loader capable of reciprocating between an unloading position on the stocker side and a loading position on the pallet side, and a lifter in the loader. As the loader moves from the unloading position toward the loading position, the lifter lowers and feeds the disk on the selected shelf to the pallet while drawing out the disk from the stocker. As the loader moves from the loading position toward the unloading position, the lifter raises and returns the disk on the pallet to the selected shelf while pushing back the disk toward the stocker.

    • A semiconductor memory device in which erroneous operation with respect to undesired level changes of the input address signal is prevented, and appropriate operation of the main amplifier is ensured. The semiconductor memory device has a main amplifier activating pulse generator 112' which includes response sensitivity reduction circuit 10, response sensitivity selector 12, and main amplifier activating pulse generator 14. The response sensitivity reduction circuit 10 can reduce the response sensitivity or input sensitivity of the circuit 112' with respect to an input address transition detection pulse ATD. The response sensitivity selector 12 selects either a first input terminal A1 or a second input terminal A2, depending on the output state of the main amplifier activating pulse generator 14. Consequently, when there is no output of a main amplifier activating pulse MA from the main amplifier activating pulse generator 14, the response sensitivity selector 12 switches to first input terminal A1 to select response sensitivity reduction circuit 10; when a main amplifier activating pulse MA is output, the selector 12 switches to second input terminal A2 to select bypass circuit 11.
