RAM is an acronym for Random Access Memory, memory which can be read from and written to at any time. The Channel F has 64 scratch-pad registers which can be written and read like RAM through the ISAR and register opcodes, and 128x64 bytes of VRAM that stores the on-screen image by outputting through the ports. In the Channel F the VRAM is not hooked up to be read back and the left over space can't be used for temporary storage.
The original SABA Videoplay 20, Schach, has 2KiB RAM that are often used by homebrews.
