<P>PROBLEM TO BE SOLVED: To positively avoid a software error caused by radial rays without degrading access performance by inserting an error correction circuit. <P>SOLUTION: A memory cell has: a capacitor A14 connected, through a transistor A11, to a bit line D941; a capacitor B15 connected, through a transistor B12, to the bit line D941; and a capacitor C16, connected, through a transistor C13, to a bit line E942. The on/off of the transistors, A11, B12, and C13 is controlled through a common word line. Consequently, the capacitor A14 has a capacity smaller than that of the capacitor C16, the capacitor B15 has a capacity smaller than that of the capacitor C16, and the sum of the capacities of the capacitors A14 and B15 is made larger than the capacity of the capacitor C16. <P>COPYRIGHT: (C)2004,JPO&NCIPI |
