    摘要: On a semiconductor substrate, there are formed a first macro cell having wiring layers of three layers each formed of a metal wiring layer (for example, an aluminum wiring) and a second macro cell having wiring layers of three layers each formed of a metal wiring layer similar to the first macro cell. The first macro cell is formed to have a wiring structure of three wiring layers though the originally necessary number of metal wiring layers is two. The metal wiring layer of each layer on the first macro cell is formed of the same material as the metal wiring layer of the corresponding each layer on the second macro cell. Moreover, the metal wiring layer of each layer is formed to have the same film thickness. In order to connect the first and second macro cells to each other, a macro interconnection wiring is formed to be included in the third wiring layer (uppermost wiring layer).

    摘要: A semiconductor memory device includes a memory cell array, row decoder, bit line pairs, sense amplifier, sense amplifier control circuit, data latch, transfer gate, transfer gate control circuit, and write circuit. The memory cell array has dynamic memory cells arranged in an array form. The row decoder decodes a row address signal to select a desired one of rows of the memory cell array. Each of the bit line pairs is connected to those of the memory cells which are arranged on a corresponding one of columns of the memory cell array. The sense amplifier amplifies data read out on the paired bit lines and positively feeding data back to the paired bit lines to hold the data. The sense amplifier control circuit controls the operation of the sense amplifier. The data latch latches readout data and write data. The transfer gate transfers data between the data latch and the sense amplifier. The transfer gate control circuit controls the transfer gate. The write circuit writes data into the data latch in synchronism with a clock signal. At the time of writing data into the memory cells, data is previously supplied to the data latch by the write circuit and latched in the data latch, and after the transfer gate control circuit controls the transfer gate to supply data to the bit line pairs from the data latch, the sense amplifier control circuit activates the sense amplifier.

    摘要: A semiconductor device of a memory-macro type can be designed within a short time to have a desired storage capacity, which does not occupy a large area, so as to reduce the chip cost. The semiconductor device includes a memory macro having sub-memory macros, each sub-memory macro having a DRAM memory-cell array, and a row decoder and a column decoder for selecting any desired memory-cell from the memory cell of the array. The memory macro also includes a control-section macro having a DC potential generating circuit for generating various DC potentials required to drive the sub-memory macros. At least one of the sub-memory macros is combined with the control-section macro to form the memory macro as a one-chip memory capable of storing an integral multiple of N bits.

    摘要: A data register that stores the data corresponding to the selected memory cell in a memory cell array is provided near the memory cell array. A decoder that selects the data from the data register starts decoding in response to an address signal accessing the memory cells in synchronization with a clock signal determining the operation period. In the first half of an operation period of the clock signal, the decoder outputs a signal in response to a signal corresponding to the address signal determined in the preceding operation period. According to the output of the decoder, the data register is selected. In the latter half of the operation period, a signal corresponding to a new address signal for the next operation period is transferred to the decoder. By doing this, the output control signal in the decoder is caused to synchronize with a signal driving an address signal, enabling the proper address to be selected without fail.

    摘要: When memory cells enter an operation mode which performs only data holding, a control circuit controls the memory cells and an ECC circuit as follows. A plurality of data are read out to generate and store a check bit for error detection and correction. Refreshing is performed in a period within the error occurrence allowable range of an error correcting operation performed by the ECC circuit by using the check bit. Before a normal operation mode is restored from the operation mode which performs only data holding, an error bit of the data is corrected by using the check bit. In an entry/exit period, read/write and an ECC operation are sequentially performed for all the memory cells by a page mode operation. Memory cells connected to a word line which is not accessed by the page mode operation are sequentially activated and refreshed.
