According to one embodiment of the invention, an electronic device, such as a tablet PC for example, is designed with a housing and a cover configured for attachment to the housing. The housing includes a front panel and a back panel having a base unit with a recess to receive a stylus pen to operate as a leg to maintain the housing in an upright position. Alternatively, the housing may include a control button to receive a stylus pen so that the combination operates as an input device similar to a joystick.

A displacement sensor for sensing the relative position of an object to be detcted is provided. The displacement sensor includes a core body having a core center portion and core end portions that are continuously formed on both sides of the core center portion. Magnetizing coils and detecting coils are wound around the core body such that they are lined on an axis of the core body. One of the magnetizing coils and detecting coils is placed at the core center portion while the other ones of the magnetizing coils and detctin coils are placed at the core end portions in the axial direction. The width of the core end portions in the direction perpendicular to the axial direction of the core body is substantially the same and is smaller than the width of the core center portion.

The time required for the program verify and erase verify operations can be shortened. The change of threshold values of memory cells can be suppressed even if the write and erase operations are executed repetitively. After the program and erase operations, whether the operations were properly executed can be judged simultaneously for all bit lines basing upon a change, after the pre-charge, of the potential at each bit line, without changing the column address. In the data rewrite oepration, the rewrite operation is not effected for a memory cell with the data once properly written, by changing the data in the data register.

A non-volatile semiconductor memory device comprises a memory cell array of data-rewritable non-volatile memory cells or memory cell units containing the memory cells, and a plurality of word lines each commonly connected to the memory cells on the same row in the memory cell array. In write pulse applying during data writing, a high voltage for writing is applied to a selected word line, and an intermediate voltage for writing is applied to at least two of non-selected word lines. The beginning of charging a first word line located between the selected word line and a source line to a first intermediate voltage for writing is followed by the beginning of charging a second word line located between the selected word line and a bit line contact to a second intermediate voltage for writing.

A semiconductor memory device disclosed herein comprises a memory cell array in which memory cells are arranged in a matrix and a row decoder circuit for selecting a word line in this memory cell array and for applying a voltage to the selected word line. The decoder circuit includes a plurality of first transistors of a first conductivity type in which one end of each current path is directly connected to each of the word lines, and a second transistor of a second conductivity type opposite to the first conductivity type for applying a voltage to a gate of the first transistor connected to a selected word line at the time of the operation for applying a voltage to the selected word line. The application of a voltage to the selected word line is performed only by the first transistor of the first conductivity type.

A voltage switching circuit is disclosed which is constructed from a minimum number of transistors and prevents the threshold voltage margin from being lowered by causing high-voltage cutoff and supply voltage transfer functions heretofore performed by a single depletion transistor to be shared between two series-connected depletion transistors different in gate insulating film thickness or threshold voltage. Thus, without using enhancement transistors which involve an increase in pattern area a voltage switching circuit can be provided which is small in chip area, low in cost and high in yield and reliability and provides a stable operation with a low supply voltage which is impossible with one depletion transistor.

A non-volatile semiconductor memory includes a memory cell array having a plurality of electrically-rewritable non-volatile memory cells. The memory cell array is provided with an initially-setting data area, programmed in which is initially-setting data for deciding memory operation requirements. The non-volatile semiconductor memory also includes an initial-set data latch. The initially-setting data of the memory cell array is read out and transferred to the data latch in an initially-setting operation.
