A memory capable of suppressing increase of the chip area thereof while increasing a read voltage is obtained. This memory comprises a memory cell array including a plurality of subarrays, a sub bit line arranged on each subarray and provided to be connectable to a main bit line, a storage portion connected between the word line and the sub bit line and a first transistor having a gate connected to the sub bit line and a first source/drain region connected to the main bit line for controlling the potential of the main bit line on the basis of the potential of the sub bit line in a read operation. |
