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

摘要

A removable electronic circuit card (33) having multiple modules, such a memory module with a non-volatile mass storage memory and a separate input-output (37a) 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 (31) 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.
