摘要： An electronic card with dynamic memory allocation management is provided, which requires only one single memory by utilizing a dynamic memory controller having a selector and a first, a second and a third base registers. A first DMA controller provides an output address added to the first base register for performing data access. A micro-controller provides an output address added to the second base register for performing data access. A second DMA controller provides an output address added to the third base register for performing data access. When the micro-controller, the first DMA controller or the second DMA controller issues an access request to the memory, the dynamic memory controller selects one of the micro-controller, and the first and second DMA controllers to access the memory based on a sequence of the access requests.

摘要： A simulation SmartMedia/xD-Picture memory card capable of using various kinds of non-volatile memory has at least one non-volatile memory chip for storing data; a card interface and a controller. The card interface is defined with command, data and address signal for enabling an external host computer to access the data in the non-volatile memory chip. The controller is used for interpreting a command sent from the host computer and changing an address sent from the host computer to a valid address for the non-volatile memory chip to go to the non-volatile memory chip to write, read or delete the data.
