Abstract
A static-type RAM device in which the amplitude of the data signal stored in a memory cell just after the writing in of data is completed is increased and the stability of the data stored in each memory cell is increased. The RAM device includes a bit-line pulling-up circuit for pulling up the potential of a bit line to a voltage which is approximately equal to or larger than the power supply voltage and a word-line pulling-up circuit for pulling up the potential of a selected word line to a voltage which is larger than the power supply voltage after the writing in of data is completed.
