Abstract:
A magnetic random access memory comprising:a plurality of word lines; a plurality of sense lines; a matrix array of memory cells, each memory cell being located on an intersection of a corresponding one of said word lines and a corresponding one of said sense lines, each memory cell including a magnetoresistance element and a switching element which establishes a connection between the corresponding sense line and the magnetoresistance element when the corresponding word line is addressed; a plurality of sense circuits respectively corresponding to said sense lines, each sense circuit including a capacitive element connected to the corresponding sense line and a switching element for applying a voltage to the capacitive element and discharging energy stored in said capacitive element when the corresponding sense line is addressed; and a plurality of voltage control elements respectively connected in said sense lines for maintaining the sense lines at constant lower voltages regardless of higher voltages respectively produced by said sense circuits.
