Abstract
A programming operation and a verification operation are executed in divided parts or pages, while being alternately shifted one from the other. As a result, the number of memory transistors at the time of the programming operation is reduced, such that the current used at the time of the programming operation is reduced, and the current supply capability of a step-up circuit can be lowered.
