Thus, even when a power source voltage is different at the time of writing and reading, the front step gate can always absorb the current of a constant value. Then, a pattern area can be prevented from being enlarged on the basis of the current capacity increase processing of a transistor for front step gate or an access time can be prevented from being delayed on the basis of pressure resistance improving processing.
