Abstract
An SD memory card contains an RF circuit, a controller LSI and a flash memory. The RF circuit is connected to an antenna module attached to the SD memory card. The controller LSI executes radio interface control and interface control for the SD memory card. By running a protocol control program and an SD memory card interface control program stored in a ROM, using an MPU, the controller LSI executes upper-protocol control and SD memory card interface control (security data access control, flash memory access control).
Claims12
A memory card for insertion into a card slot of a host device, comprising:
- a memory device;
- a plurality of signal pins configured for connection to the host device inside the card slot and include a data pin that receives data from the host device;
- a controller configured to control access to the memory device and to write the data received from the data pin in the memory device;
- and
- a connector that is attachable to and detachable from an antenna provided in the host device, the connector provided on a side of the memory card where the plurality of signal pins connect to the host device, wherein the connector contacts the antenna inside the card slot if the memory card is inserted into the card slot and the connector is detached from the antenna if the memory card is removed from the card slot.
