Abstract
A memory card module includes a first circuit board, and a second circuit board. On one surface of the first circuit board, there are flash memories and a controller. The second circuit board is installed at one end of the first circuit board and is electrically connected with the first circuit board so as to form a transmitting interface port. On a first surface of the second circuit board, there are a plurality of interface connecting points. On a second surface of the second circuit board, part of the second surface is hollowed out. A space formed between the hollowed out area and the corresponding first circuit board increases the area for circuit layouts and the mounting components for the first circuit board. Therefore, quantity of accommodated memory components may be increased so as to increase the total storage capacity of the memory card under limitation of small dimensions.
