Regular data inputted / outputted to / from external terminals is read / written to / from a regular cell array, and parity data is read / written from / to a parity cell array. Since the parity data is generated by a parity generation circuit, it is difficult to write a desired pattern to the parity cell array. The regular data and the parity data are exchanged with each other by a switch circuit, so that the regular data can be written to the parity cell array and the parity data can be written to the regular cell array. This enables the write of desired data to the parity cell array. A test of the parity data can be easily conducted.

HfO2 films and ZrO2 films are currently being developed for use as capacitor dielectric films in 85 nm technology node DRAM. However, these films will be difficult to use in 65 nm technology node or later DRAM, since they have a relative dielectric constant of only 20-25. The dielectric constant of such films may be increased by stabilizing their cubic phase. However, this results in an increase in the leakage current along the crystal grain boundaries, which makes it difficult to use these films as capacitor dielectric films. To overcome this problem, the present invention dopes a base material of HfO2 or ZrO2 with an oxide of an element having a large ion radius, such as Y or La, to increase the oxygen coordination number of the base material and thereby increase its relative dielectric constant to 30 or higher even when the base material is in its amorphous state. Thus, the present invention provides dielectric films that can be used to form DRAM capacitors that meet the 65 nm technology node or later.
