The Sub Screen is a virtual render target used in Color Math. It is not a framebuffer, but a circuit.
Some game instruction booklets (for example FF3, Chrono Trigger, and A Link to the Past) call the pause screen the "Sub Screen" but actually display it on the color math main screen. The Legend of Zelda for the NES called the screen where the player chooses which item to equip the "subscreen," so perhaps Nintendo decided to overload that term when designing the SNES PPU.
