[0003] But, generally speaking, small memory card, because its cover size and thickness are determined by the standard, so can only be mounted on the substrate of the IC chip that is used to control memory chip in the small memory card so memory chip is installed, will be greatly increased. It is difficult to increase the storage capacity above

no. 1 Embodiment

[0143] As a small memory card as an example of the card-type recording medium related to the first embodiment of the present invention, such as Figure 1 ~ Figure 3 As shown, a basic substrate module 210, a first memory module 221 mounted on the basic substrate module 210, and a second memory module 222 mounted on the first memory module 221 are provided to form a Figure 24 The substrate 110 on which the above-mentioned control LSI switch 113, microprocessor IC chip 114 and flash memory chip 115 are installed is installed in the upper cover 30 and the lower cover 31, and the space left between each cover 30, 31 in each given gap.

[0144] The basic substrate module 210 is formed by mounting the IC chip 14 for a microprocessor and the IC chip 13 for an ASIC at predetermined intervals on the lower surface of the rectangular plate-shaped substrate 10 . Make each electrode of IC chip 14 for microprocessor and each substrate electrode, and, each electrode of ASIC IC chip 13 and e...

Abstract

The present invention provides a card-type recording medium capable of increasing memory capacity, excellent in rigidity, and good in impact resistance, and a method for manufacturing the same. A memory module (221, 222, 270) constituted by mounting a plurality of memory chips (15) on a memory substrate (21, 22, 70, 63, 65) is mounted on one surface of a base substrate (10) , and the IC chips (13, 14, 60) for controlling the operation of the plurality of memories are installed on the other surface of the above-mentioned base substrate (10), and the whole is installed in the cover (30, 31).

Description

technical field [0001] The present invention relates to a card-type recording medium in which a memory chip is mounted on at least one side of a base substrate and an IC chip for controlling the operation of the memory chip is mounted on the other side. Background technique [0002] Heretofore, as an example of such a card-type recording medium, a compact memory card having a semiconductor memory chip such as a flash memory is known. Such a small memory card tends to be particularly used in portable devices for excellent portability, and it is desired to record still pictures, moving pictures, music, etc. for communication between portable devices. Therefore, as a compact memory card, it is desired to have a larger storage capacity. [0003] But, generally speaking, small memory card, because its cover size and thickness are determined by the standard, so can only be mounted on the substrate of the IC chip that is used to control memory chip in the small memory card so memo...
