A semiconductor memory device includes an I/O line for transmitting read data that has been read from a memory cell, a plurality of driver circuits for driving the I/O line on the basis of the read data, a read circuit for receiving the read data transmitted through the I/O line, and an assist circuit for amplifying the read data transmitted through the I/O line. The assist circuit is disposed farther away from a prescribed drive circuit included in the plurality of drive circuits as viewed from the read circuit. The signal level can thereby rapidly change levels even in memories having relatively long I/O lines.

According to one embodiment of the present disclosure, a redox flow battery is provided comprising an ionically conductive separator, a working side flowing electrolyte, a working electrode in ionic contact with the working side of the ionically conductive separator and the working side flowing electrolyte, a counter electrode, and an auxiliary electrode peripherally circumscribed by the working electrode in a common layer of the flow battery.
