A method for processing a separation and rupture portion of a display label is a method for forming, on the display label attached to an attachment target object, the separation and rupture portion for rupturing the display label upon separation of the display label from the attachment target object. This method includes attaching, to the attachment target object, the display label having a back side on which an adhesive layer is formed, and then forming a slit serving as the separation and rupture portion on the display label.

摘要:
A semiconductor integrated circuit has a central processing unit and a rewritable nonvolatile memory area disposed in an address space of the central processing unit. The nonvolatile memory area has a first nonvolatile memory area and a second nonvolatile memory area, which memorize information depending on the difference of threshold voltages. The first nonvolatile memory area has the maximum variation width of a threshold voltage for memorizing information set larger than that of the second nonvolatile memory area. When the maximum variation width of the threshold voltage for memorizing information is larger, since stress to a memory cell owing to a rewrite operation of memory information becomes larger, it is inferior in a point of guaranteeing the number of times of rewrite operation; however, since a read current becomes larger, a read speed of memory information can be expedited. The first nonvolatile memory area can be prioritized to expedite a read speed of the memory information and the second nonvolatile memory area can be prioritized to guarantee the number of times of rewrite operation of memory information.
摘要:
A microcomputer capable of on-board programming of dedicated user communication protocols without requiring a serial interface on the mounted board, and that will not destroy the dedicated user communication protocol code even if the system runs out of control. A user boot mat other than a user mat is provided for programming control programs for the user in the on-chip non-volatile memory of the microcomputer. The user boot mat serves as the mat for programming the dedicated user communication protocol and also provides a user boot mode for running the program. The user boot mat cannot program or erase in this user boot mode. By separating the user boot mat and user mat, an interface capable of programming and erasing the user-specified programming can be achieved without having to program a dedicated communication protocol on the user mat.

A data processing apparatus supplied a first voltage from outside, includes a CPU, a first voltage generating circuit, a second voltage generating circuit, a clock generating circuit, and, a nonvolatile memory which can be accessed by the CPU. The first voltage generating circuit generates a second voltage, a voltage level of which is lower than that of the first voltage. The clock generating circuit is supplied the second voltage from the first voltage generating circuit and generates a clock signal, and the second voltage generating circuit is supplied the second voltage from the first voltage generating circuit and the clock signal from the clock generating circuit, and generates a second voltage, a voltage level of which is higher than that of the first voltage, for supplying to the nonvolatile memory.
摘要:
A microcomputer incorporating a flash memory which is erased and programmed electrically in a stable manner within a relatively wide range of external power supply voltages including those for low-voltage operations. The microcomputer comprises a voltage clamp unit including a reference voltage generating circuit and a constant voltage generating circuit. In operation, the voltage clamp unit generates a voltage of a low dependency on a supply voltage and clamps the generated voltage to a voltage level which, within a tolerable range, is lower than a single supply voltage externally furnished. This prevents voltages boosted by boosting circuits operating on the clamped voltage, i.e., programming and erasure voltages, from being dependent on the externally supplied voltage.

A first conductive layer and a second conductive layer are formed apart from each other on a surface of a semiconductor substrate. A first contact hole for exposing a surface of first conductive layer is formed in an interlayer insulating film. A first interconnection layer is buried in first contact hole so as to be in contact with first conductive layer. The position of the surface of first interconnection layer is the same as or lower than the surface of interlayer insulating film. The surface of first interconnection layer is covered with an insulating film. A second contact hole for exposing a surface of second conductive layer is provided in interlayer insulating film. A second conductive layer is connected to second conductive layer through second contact hole.
