摘要：
A semiconductor memory device has a read data line, a write data line, a data holding circuit, and a data writing circuit. The data holding circuit holds data on the write data line, and the data writing circuit writes the data held on the write data line into a memory cell. Further, a semiconductor memory device has a read data line, a write data line, and an address information holding circuit. The address information holding circuit holds address information that is input in relation to write data, and when an access occurs to the address held in the address information holding circuit, data held on the write data line is written into a memory cell corresponding to the address.
