A memory card designed for the Sega Mega-CD that plugs into the Sega Mega Drive cartridge port. It is for use with Mega CD games which require the user to save, as unlike ROM cartridges, there is no way of saving data on the disc itself. The unit contains 2045 blocks (1 Mbit) of memory for game saves. While the only officially-released RAM cartridge for the Sega CD has a capacity of 1 Mbit (128 KB; 2045 blocks), the system actually supports up to 4 Mbit (512 KB; 8189 blocks). The memory size is specified by a 3-bit value mapped to Main 68000 address $400001. This value indicates the memory size as a power of two, multiplied by the base memory size of 8 KB.
