MULTI-MODULE CIRCUIT CARD WITH INTER-MODULE DIRECT MEMORY ACCESS

摘要

A removable electronic circuit card having multiple modules, such a memory module with a non-volatile mass storage memory and a separate input-output module, where data transfers may be made through the a first module directly to and from the another in a direct memory access (DMA) type transfer when the card is inserted into the host system but without having to pass the data through the host system. Once the host gives a DMA command, the data transfer is accomplished independently of the host system, except for the host supplying power and possibly a clock signal and other like support, during such a data transfer directly with card. The data for the transfer can be communicated between the input-output module and the exterior device through either wireless or an electrical connection means.
