The semiconductor integrated circuit device includes: a first latch which can hold an output signal of the X decoder and transfer the signal to the word driver in a post stage subsequent to the X decoder; a second latch which can hold an output signal of the Y decoder and transfer the signal to the column multiplexer in the post stage subsequent to the Y decoder; and a third latch which can hold an output signal of the sense amplifier and transfer the signal to the output buffer in the post stage subsequent to the sense amplifier. The structure makes it possible to pipeline-control a series of processes for reading data stored in the non-volatile semiconductor memory, and enables low-latency access even with access requests from CPUs conflicting.

This invention is to reduce the number of memory gate drivers, while lessening the number of times of disturb occurrence in a memory array configuration that implements writing in small byte units. A memory array comprises a plurality of sub-arrays, MG transfers, SL drivers, and CG drivers. Each sub-array includes a plurality of memory gate lines, control gate lines, source lines, and bit lines. Memory cells are arranged in positions of intersections of these lines. The control gate lines, CG drivers, source lines, and SL drivers are common to the sub-arrays, whereas the memory gate lines and MG buffer circuits are provided for each sub-array. Thereby, the units in which data is written are decreased and adverse effects of disturb are reduced without increasing the circuit size of the memory array.

Vertical MISFETs are formed over drive MISFETs and transfer MISFETs. The vertical MISFETs comprise rectangular pillar laminated bodies each formed by laminating a lower semiconductor layer (drain), an intermediate semiconductor layer, and an upper semiconductor layer (source), and gate electrodes formed on corresponding side walls of the laminated bodies with gate insulating films interposed therebetween. In each vertical MISFET, the lower semiconductor layer constitutes a drain, the intermediate semiconductor layer constitutes a substrate (channel region), and the upper semiconductor layer constitutes a source. The lower semiconductor layer, the intermediate semiconductor layer and the upper semiconductor layer are each comprised of a silicon film. The lower semiconductor layer and the upper semiconductor layer are doped with a p type and constituted of a p type silicon film.

The semiconductor device includes a nonvolatile memory, having a memory array containing 1-bit twin cells, each composed of electrically rewritable first and second storage devices, the first and second storage devices holding binary data according to difference of their threshold voltages, and having different retention characteristics depending on difference of the binary data thereof; a read circuit for differentially amplifying complementary data output from the first and second storage devices of the twin cell selected for read, and judging information stored in the twin cell; and a control circuit. Two memory cells constituting a twin cell are arranged to hold different data. Therefore, even when the retention performance of one memory cell deteriorates, the difference between data held by the two memory cells can be maintained. Hence, differential amplification of such difference enables acquisition of proper stored information. Thus, retention performance of an electrically rewritable nonvolatile memory cell is improved.

The degree of integration and the number of rewriting of a semiconductor device having a nonvolatile memory element are improved. A first MONOS nonvolatile-memory-element and a second MONOS nonvolatile-memory-element having a large gate width compared with the first MONOS nonvolatile-memory-element are mounted together on the same substrate, and the first MONOS nonvolatile-memory-element is used for storing program data which is scarcely rewritten, and the second MONOS nonvolatile-memory-element is used for storing processed data which is frequently rewritten.

The apparatus includes a holder holding an optical element, a back plate supporting the optical element via the holder, a mechanism moving the optical element in a six-degree-of-freedom, a base plate supporting the back plate via the mechanism, and six displacement sensors disposed on the base plate and measuring displacement amounts of different points on the optical element. The displacement sensors includes three ones measuring them in a first direction, one measuring it in a second direction, and two ones measuring them in a third direction. The apparatus further includes a transformation processor transforming the six measured displacement amounts into displacement amounts of the optical element in the six-degree-of-freedom, a calibration processor calibrating the transformed displacement amounts, and a controller outputting command values to the displacing mechanism based on differences between the calibrated displacement amounts and target displacement amounts of the optical element.

The present invention provides a drive mechanism having a high rigidity and capable of performing fine adjustment in 6-axis directions of an optical element such as a mirror or a lens, or a support member for supporting the optical element, in optical equipment such as an exposure device. The drive mechanism has such a feature that three monolithic planar 3-joint or 4-joint link mechanisms are each arranged between a movable portion and a stationary portion through the intermediation of a bearing having at least one degree of freedom of rotation.
