"Outer banks" are things you find in the multicart mappers, where individual games write to the registers of the "regular" mapper and the menu writes to a separate set of registers that chooses which game will be played. For example, Nintendo World Cup appeared on two boards that extend the MMC3 in this way: one with SMB1 and Tetris and one with Super Spike V'Ball.
This same structure occasionally shows up in ordinary single-game mappers: Bandai's Oeka Kids games, Namco's Devil Man, several other Namco games, and a few HKOs that would like better corroboration.

† Mappers 89, 93, and 184 exist as a single IC, however their functions are trivially described using a small number of 7400-series ICs, and likely contain multiple silicon dice that were wire bonded together in the same package.
‡ Mapper 93 is technically the same 89 other than mirroring, but it only commercially existed using 8kB of CHR-RAM
* the Vs System distributed its original games as five or six 8 KiB ROMs, and decoding on its mainboard allowed banking of CHR like CNROM. It is a little disingenuous to claim that 0 ICs were necessary for banking since the same functionality is not possible on a Famicom, however, banking was incrementally free.
§ Doesn't have CHRROM, hence "-1" ICs
