Thus, there is a problem that there is {TAIL ~ generated deviation} in the timing of discharge in {HEAD ~ both sense terminals} of the sense amplifier after the read target memory cell and the reference cell selection transistor are activated in the above reading operation, which may cause erroneous reading
