Abstract
A memory includes a plurality of cells arranged in a matrix having a plurality of rows and a plurality of columns, wherein each cell is capable of storing a bit. Each cell is coupled between a first power supply node that receives a power supply voltage and a second power supply node that receives a second voltage. A plurality of word lines are associated with the memory cells and supplied by a third voltage in read or write operation. The third voltage is a suppressed power supply voltage. The second voltage is negative in read operation and positive in write operation.
