<p><P>PROBLEM TO BE SOLVED: To provide a stacking small-sized memory card increasing its reliability and use-life and being convenient for its manufacture. <P>SOLUTION: The stack type small-sized memory card has an upper-layer memory card and a lower-layer memory card. A first heatsink and a second heatsink are formed to the upper-layer memory card and the lower-layer memory card, respectively. The first heatsink and the second heatsink are superposed mutually. The stack type small-sized memory card is formed so that the amount of heat of the upper-layer memory card and that of the lower-layer memory card are dissipated from the first heatsink and the second headsink, respectively. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
