Abstract
A semiconductor device includes: a plurality of memory cells; a plurality of local bit lines connected to respective memory cells of the plurality of memory cells; and a first amplifier. The first amplifier receives read data from each local bit line of the plurality of local bit lines and determines a transition speed of an output level of the first amplifier in response to receiving a combination of at least two pieces of read data. The first amplifier transfers, based on the determined transition speed, multivalued data of the read data to a read global bit line.
