That’s a somewhat misleading way to describe it. The N64 has 4K texture memory (TMEM), but you can use far more than 4K of texture during a frame—because you can load data into TMEM as many times as you like during a frame. In practice, you might think of TMEM like it’s a cache, it’s just that you have to manage this cache manually. You can use as much RAM as you like for textures. TMEM is also not part of main RAM, like the RSP’s DMEM and IMEM.
