SECURE DIGITAL CARD WITH TWO MICRO-SD CARDS IN STRIPING DATA ACCESS

摘要

The present invention constructs a SD Flash card by plugging two micro-SD cards into a new apparatus that has the same form factor as a SD Flash card. In this new apparatus, there is a controller to bridge the two micro-SD cards of any SD interface speed type (DS, HS, UHS50 or UHS104) to UHS104. The controller performs striping access function to achieve almost double performance in sequential read/write throughput if it is not limited by the target SD interface speed.
