Abstract
A memory includes a cell array; bit lines; word lines; sense amplifiers; first determination transistors receiving information data and making a connection between a first voltage source and a first determination node be in a conductive or a non-conductive state based on a logic value of the information data; second determination transistors receiving the information data detected by the sense amplifiers and making a connection between the first voltage source and a second determination node be in a conductive or a non-conductive state based on the logic value of the information data; a second voltage source charging the first and the second determination nodes; and a determination unit detecting potentials of the first determination node and the second determination node when a logic of the information data is inverted logically to determine maximum and minimum values of potential of the information data.
