摘要： The objective of the invention is to provide a type of semiconductor memory device equipped with an error correction circuit 200 characterized by the fact that it can perform correction of errors in stored data without increasing the circuit size and power consumption, and without decreasing operating speed. An error correction code EC corresponds to data stored in sub-memory 120 separate from main data stored in main memory 110. In read mode, the main data and error correction code are read from the main memory and sub-memory, respectively. On the basis of these data, the error correction code is generated for correcting errors in the read data. Error correction circuit 300 corrects errors in the main data. By storing the error correction code in a sub-memory different from the main memory and selecting the appropriate layout of the main memory and sub-memory, it is possible to increase the reading speed of the error correction code and to suppress time delays caused by error correction.

摘要： A semiconductor circuit which can restrain increase in manufacturing cost and layout area to a minimum level and can realize high speed and low power consumption. Bias voltages with different levels are generated corresponding to a mode control signal by a bias voltage supply circuit comprising PMOS transistors P2 and P3 which have different voltages applied to the respective sources and the mode control signal input to the gates. The generated bias voltages are supplied to the n-wells of PMOS transistors. During operation, a bias voltage that is almost the same as the operation voltage is applied to the n-wells of PMOS transistors. During standby, a bias voltage higher than the operation voltage is supplied to the aforementioned n-wells of PMOS transistors. In this way, the driving currents of the transistors can be kept at a high level during operation, while leakage currents of the transistors can be restrained during standby. Consequently, high speed and low power consumption can be realized.
