    摘要: Semiconductor device according to the present invention includes package frame, bonding wire, pad, first internal power supply line, second internal power supply line, internal circuit, stabilize circuit, GND package frame, GND bonding wire, GND pad, and internal GND line. Bonding wire, pad, and first and second internal power supply lines function as a filter. As a result, noise generated by operation of the internal circuit is absorbed in propagating to the stabilize circuit through first internal power supply line, pad, and the second internal power supply line. Therefore, effects of noise given to the stabilize circuit are small.

    摘要: For each memory block, a predecoder for predecoding an applied address signal, an address latch circuit for latching the output signal of the predecoder, and a decode circuit for decoding an output signal of the address latch circuit and performing a memory cell selecting operation in a corresponding memory block are provided. Propagation delay of latch predecode signals can be made smaller and the margin for the internal read timing can be enlarged. In addition, the internal state of the decoder and memory cell selection circuitry are reset to an initial state when a memory cell is selected and the internal data output circuitry is reset to an initial state in accordance with a state of internal data reading. Thus, a non-volatile semiconductor memory device that can decrease address skew and realize an operation with sufficient margin is provided.

    摘要: In an exclusive OR circuit (XOR gate) constituting an ECC circuit, the drivability of P channel MOS transistors is set larger than the drivability of N channel MOS transistors. Accordingly, the speed of the logic level of an output node being set to an H level from an L level identified as a reset state is increased than the case where the drivability is set equal. Thus, the time required to output a syndrome from a plurality of stages of XOR gates can be reduced to allow execution of error correction processing at high speed.

    摘要: In a memory cell array of an MRAM, a normal memory cell is compared with a reference memory cell which holds a reference value, thereby storing data of one bit per cell. Two spare memory cells store data of one bit as a whole. By writing complementary values to the two spare memory cells and connecting these spare memory cells to a sense amplifier, the stored data of one bit is read. A spare memory cell section which is often arranged in an array peripheral portion becomes more resistant against a variation in finished dimensions of elements and a success rate for replacing and relieving a defective memory cell by a spare memory cell increases.

    摘要: Dummy cells are disposed in alignment with memory cells arranged in rows and columns in a memory array. The memory cell includes a variable resistance element and a select transistor having a collector connected to a substrate region and selecting the variable resistance element in response to a row select signal. Corresponding to a row of memory cells, there is provided a word line connecting to memory cells on corresponding row and transmitting the row select signal, and a word line shunting line electrically connected at predetermined intervals to each word line. Moreover, corresponding to a row of dummy cells and a column of dummy cells, there is provided substrate shunt lines electrically connected to the substrate region. The voltage distribution in the substrate region is eliminated to achieve stable operating characteristics of the memory cell transistor. In addition, a word line is driven at high speed by a word line shunt structure.
