  • Patent number: 6983402
    Abstract: In a computer device, a latch circuit latches a program read from a ROM. Even when a program C is mistakenly read from the ROM in place of a correct program B, a CPU outputs an access signal to the ROM again to read the program B at the same address from the ROM, and a match detection circuit compares the program B with the program C output from the latch circuit. Since these programs fail to match with each other, the CPU outputs the access signal again. If the ROM outputs the program B correctly this time, the program B matches with the program B output from the latch circuit when the match detection circuit compares these programs. The CPU then executes the program B as correctly read ROM data. Thus, even when a program in the ROM is mistakenly read, safe operation by a correctly read program is ensured.

  • Patent number: 6721903
    Abstract: An inventive information processor performs a predetermined process substantially continuously without causing runaway in its CPU even if extraneous noise has entered the power supply terminal thereof. When the incoming noise reaches relatively low Level 1(L), important information, determining the state of the CPU, is protected by saving it on a register. Thereafter, when the noise level exceeds Level 1(H), important information, representing the status of the predetermined process, is protected by storing it on a memory. Subsequently, when the noise level reaches Level 2, the CPU is suspended. And when the noise has decreased to less than Level 1(L), the predetermined process is resumed in accordance with the information saved and protected on the register and memory. Accordingly, even if noise has entered, the predetermined process can be continued without causing runway in the CPU after having been suspended for a while.

  • Patent number: 6682967
    Abstract: A semiconductor device comprises a semiconductor substrate, a p-type well formed in the semiconductor substrate, an n-type well formed in the semiconductor substrate and positioned contiguous to the p-type well, an n-type diffused region formed in the p-type well, and a p-type diffused region formed in the n-type well, wherein a corner C1 having the p-type well on the inside is present in a part of the boundary pattern between the p-type well and the n-type well. At least one of the two sides defining the corner C1 extends from a top of the corner to the n-well by a predetermined width d over a predetermined length. The particular structure permits suppressing generation of a difference in a well isolation punch-through voltage between the corner and the straight portion of the well boundary of the semiconductor device, making it possible to provide a fine device structure while ensuring a desired well isolation punch-through voltage without relaxing a design rule.

  • Patent number: 6253305
    Abstract: A microprocessor is provided for supporting reduction of codes in size, wherein instructions are extended in units of 0.5 word from a basic one word code. A word of instruction, fetched from an external memory, is transferred to a decoding register via instruction buffers and a selector both operate in units of half words, then is decoded by a decoder. A storage unit stores a state of an instruction stored in an instruction buffer. A controlling unit controls the selector so that the instructions are transferred from instruction buffers to the decoding register in units of half words based on a direction from the decoder and the states stored in the storage unit.
