Embodiment Construction

[0012] figure 1 A preferred way of implementing the adapter according to the invention is shown. The adapter 1 is realized here in the form of an SD memory card. The adapter 1 includes a main connector 2 in the form of an SD card connector. The adapter 1 comprises means to receive a memory card 3 in the form of a micro SD, which is connected via an auxiliary connector 4 . The adapter 1 comprises a chip 5 connected to the main connector 2 and the auxiliary connector 4 . Chip 5 comprises the electronic circuits of adapter 1 . exist figure 1 In a preferred manner, the electronic circuitry of the adapter 1 is all placed on a single chip, but it is also possible to distribute the circuitry over several chips.

[0013] figure 2 A functional description of the electronic circuitry on chip 5 is provided. The main connector 2 and the auxiliary connector 4 are connected on the chip by the main bus 20 and the auxiliary bus 40 respectively, said main bus 20 and auxiliary bus 40 co...

Abstract

An adapter allows to connect two electronic devices at the same port, at the same time. The device allows to actuate two devices at one single port which originally allows the connection of one single device. The adapter device includes a primary connector 2 to be connected to a host device taking up said adapter device, a secondary connector 4 to take up the memory card 3, an interrupter S1 connecting the primary connector and the secondary connector, and a device interface circuit 51 connected to the primary connector and controlling the opening and closing of the interrupter S1 depending on the commands arriving at the primary connector.

Description

technical field [0001] The invention relates to an adapter for a memory card. More precisely, it relates to an adapter that allows a second device to be connected to the memory card port in addition to the memory card. Background technique [0002] The market for memory cards has developed significantly based on the possibility of storing large amounts of data on flash cards. There are different standards for such memory cards, eg the SD standard (Secure Digital). Like all standards for memory cards, the SD standard defines the card format, connector type, and communication protocol between a host device designed to accept an SD card and the card itself. The SD standard used in this document refers to the publications of the SD Card Association, including "SD Memory Card, Physical Layer Specification", "SDHC Memory Card", "Mini SD Card", "Micro SD Card", "SDIO Card" and the specification of "SD Host Controller Specification". Furthermore, some memory card standards use e...
