Abstract
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.
Claims7
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.
An IC memory cartridge for an electronic device which includes a CPU having an accessible memory space greater than the memory space of the IC memory cartridge, and for connection to a plurality of IC memory cartridges, comprising:
- a first connector for connecting the IC memory cartridge to the electronic device;
- selection means for assigning the memory space of the IC memory cartridge to a definite region within the memory space of the CPU of the electronic device;
- and
- a second connector designed to connect to the first connector of another of said plurality of IC memory cartridges;
- wherein
- 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 is inserted into the other to permit a plurality of cartridges to be extended end-to-end in substantially the same plane.
An IC memory cartridge for an electronic device, the electronic device including a connector and a CPU having an accessible memory space greater than a memory space of the IC memory cartridge, comprising:
- a first connector for connecting the IC memory cartridge to the connector of the electronic device or with a second connector of another of a plurality of IC memory cartridges;
- selection means for assigning the memory space of the IC memory cartridge to a definite region within the memory space of the CPU of the electronic device;
- and
- a second connector designed to mate with a first connector of another of said plurality of IC memory cartridges;
- wherein
- 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 is inserted into the other to permit a plurality of cartridges to be extended end-to-end in substantially the same plane.
A method for providing a plurality of external IC memory cartridges to an electronic device, the electronic device including a connector a CPU having an accessible memory space greater than a memory space of one of the IC memory cartridges, the method comprising the steps as follows:
- providing two connectors to each of the IC memory cartridges, 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;
- providing selection means to each of the cartridges, each selection means provided for selectively assigning the memory space of its IC memory cartridge to a definite region within the memory space of the CPU of the electronic device;
- preparing two connecting plates each having a plurality of connectors thereon designed to mate with the connectors of the IC memory cartridges;
- connecting one or more of the IC memory cartridges between the two connecting plates;
- connecting a unit composed of the connecting plates and said one or more of the IC memory cartridges to one connector of another IC memory cartridge, the other connector of which is connected to the connector of the electronic device;
- and
- setting the selection means on each of the memory cartridges so that the memory spaces of the connected IC memory cartridges do not overlap.
