摘要:A power supply voltage control circuit supplying a power supply voltage to amemory cell array, including word lines extending along row direction, bit lines extendingalong column direction, plate lines extending along the row direction, and a plurality ofunit cells disposed at intersections of word lines and bit lines, includes a word line control
circuit for supplying a first voltage to the word lines; and a plate line control circuit forsupplying a second voltage to the plate lines; and the power supply voltage controlcircuit provides an amount of current flow from the first voltage so as to keep the firstvoltage potential almost constant during increasing a value of the second voltage in apower-on sequence, firstly increasing a value of the higher voltage of two potentialvoltages: the first voltage and the second voltage capacitive coupled, and then increasinga value of the lower second voltage.
