ABSTRACT:
A memory device includes a power supply line, a memory cell, a memory cell power supply node provided between the memory cell and the power supply line, a first voltage generating circuit coupled to the memory cell power supply node for supplying the memory cell power supply node with a first potential lower than a potential of the power supply line for a first period corresponding to at least a part of a writing operation period, and a second voltage generating circuit that is coupled to the memory cell power supply node for supplying the memory cell power supply node with a second potential lower than the potential of the power supply line for a second period corresponding to at least a part of the writing operation period.
