ABSTRACT:
A semiconductor memory having a function that set/reset information is directly written into each of the memory cells is disclosed. The semiconductor memory device of the present invention comprises word lines, bit lines, set/reset lines and switch circuits each of which is coupled to one of the set/reset lines for applying either a first potential or a second potential in response to a control signal. The semiconductor memory device further includes memory cells for storing data therein. Each of the memory cells has a first node coupled to one of the word lines, a second node coupled to one of the bit lines, a third node coupled to receive the first potential, and a forth node coupled to one of the set/reset lines.
