摘要: A circuit includes a plurality of stages each including a MOS transistor and a capacitor of which one end is connected to one of a drain and a source of the MOS transistor. The plurality of stages are connected with each other by cascade connection of the MOS transistors. A gate of the MOS transistor is connected electrically to one of the drain and the source thereof in each stage, and a substrate for at least one pair of adjacent MOS transistors are connected electrically to one of the drain and the source of one of the pair. The back bias effect is suppressed, and the layout area is reduced. Further, a plurality of booster capacitors connected in series are provided in succeeding stages, thereby suppressing degradation of breakdown voltage of each capacitor.

摘要: A nonvolatile semiconductor memory device for storing data by accumulating charge in a floating gate includes a plurality of MOS transistors sharing the floating gate. In the device, a PMOS is used for coupling during writing and an n-type depletion MOS (DMOS) is used for coupling during erasure. Coupling of channel inversion capacitance by the PMOS is used for writing and coupling of depletion capacitance by the n-type DMOS is used for erasure, thereby increasing the erase speed without increase of area, as compared to a conventional three-transistor nonvolatile memory element.

摘要: A semiconductor memory device includes: an array of memory cells that is divided into a plurality of sub-arrays; main word lines; sub-word lines; sub-word select lines; and sub-word drivers. A predetermined number of main word lines are associated with a block of sub-arrays arranged on the same row, and extend over all of these sub-arrays. A set of sub-word lines are provided per sub-array and driven by the same number of sub-word drivers corresponding thereto. Each sub-word select line consists of: a parallel portion, which is placed in parallel to the main word lines; and a plurality of vertical portions crossing the main word lines at right angles. Each sub-word driver is selected by specifying, in combination, one of the main word lines and one of the sub-word select lines. In this arrangement, a difference in signal propagation delay between a main word line and an associated parallel portion of a sub-word select line can be minimized, thus remarkably increasing the operating speed of a semiconductor memory device like a DRAM.

摘要: A video recording control device compares current and previous values indicated by an elapsed broadcast time information (TIS) of a program in an EDS (Extended Data Service) signal superimposed on a received television signal during its vertical blanking period, and controls the recording operation of a video recording apparatus employing the television signal according to the result of comparison. Therefore, the ending time of the program being recorded can be detected by utilizing the TIS of the EDS signal, and thus, even when the broadcast time of the program is extended without notifying in advance, the recording can be continued accordingly.
