    摘要: A static RAM has plurality of memory mats each including a plurality of static memory cells formed in a matrix pattern at points of intersection between a plurality of word lines and a plurality of data lines. upon receipt of an address signal into an address register, an address selection circuit selects a memory cell in one of the memory mats, and connects the selected memory cell to a sense amplifier or a write amplifier furnished corresponding to the memory mat in question. At the same time, an address counter generates an address signal corresponding to the address signal by which one of the memory mats has been selected. When a burst mode is designated by a control signal, the address signal admitted to the address register is used to select a memory cell in a first memory mat. The selected memory cell is connected to the corresponding sense amplifier or write amplifier. Then in accordance with the address signal generated by the address counter, a memory cell in another memory mat is selected and connected to the corresponding sense amplifier or write amplifier.

    摘要: A semiconductor integrated circuit with memory redundancy circuit to address the problems of increased area, power consumption and access time which is caused by using an ECC circuit for error correction. The circuit comprises: a plurality of memory mats; a local bus, parallel to word lines, which transfers read data and write data from memory cells; a global bus for writing, parallel to data lines, which transfers write data from an input pad IO; a global bus for reading, parallel to data lines, which transfers read data to an output pad IO; and at least one error correction circuit located at an intersection of the global buses and the local bus. Reading and writing may each be completed in a single cycle, and during a write operation, data which is different from data previously read is written. By this configuration, an increase in area and power consumption can be avoided and errors such as soft errors can be corrected.
