A method for providing a plurality of external IC (Integrated Circuit) cartridges to an electronic device having a CPU (Central Processing Unit) is disclosed. The IC cartridge includes first and second connectors. The first is connected to the electronic device and the second is connected to another IC cartridge and enables a plurality of IC cartridges to be connected to one electronic device. Each of the IC cartridges has a selector which selects an individual memory address. Either the IC cartridge or the electronic device has a label on which the method for setting the memory address is indicated.

A method for providing a plurality of external IC memory cartridges each having a memory space to a single connector of an electronic device which includes a CPU having an accessible memory space greater than the memory space of the IC memory cartridges, comprising steps as follows: providing first and second connectors on each IC memory cartridge, where the IC memory cartridge is rectangular in shape and said first and second connectors are provided at opposite ends of the IC memory cartridge, and said first and second connectors are designed such that one of the connectors may be inserted into the other to permit a plurality of cartridges to be extended end-to-end in substantially the same plane; provided selection means on each IC memory cartridge for selectively assigning the memory space of the IC memory cartridge to a definite region within the memory space of the CPU of the electronic device; connecting the first connector of a first IC memory cartridge to the connector of the electronic device; connecting the first connector of a second IC memory cartridge to the second connector of the first IC memory cartridge; and setting the selection means on each of the IC memory cartridges so that the memory spaces of the connected IC memory cartridges do not overlap.
