Abstract

The utility model relates to a memory card of a semiconductor, which is encapsulated in a casing of the rectangular memory card after the casing of the memory card, a flash memory, a memory control chip and a flash memory are connected with an interface circuit of the memory control chip. A set of contact chip type pin feet which are connected with a control chip are arranged on the casing of the memory card, and the arrangement orders of the pin feet are an MC1 data line interface, an MC0 data line interface, a GND ground line interface, an MC-CLK clock line interface, A VDD power supply line interface, a reserved data line interface, the reserved data line interface, the GND ground line interface, an M2 order line interface, an MC3 data line interface and an MC2 data line interface. The utility model has the advantages that the shape and the volume of the memory card are small; minimum volume can reach the length x width x height dimension of 18 mmx 12.4 mm x 1.4 mm; carrying is convenient; processing technique is simple; production efficiency is enhanced; the excellence rate of a finished product is enhanced, and simultaneously the utility model brings convenience to use.

Description

A kind of semiconductor stores card

Affiliated technical field

A kind of semiconductor memory card of the utility model, particularly a kind of semiconductor memory card that uses the FLASH flash memory.

Background technology

In the prior art, use the semiconductor memory card of FLASH flash memory, various ways and structure are arranged, as semiconductor memory cards such as PCNCIA card, SmartMedia card, CompactFLashhe and Memory Stick, though they have basic identical inner structure, but their outer enclosure and interface type of attachment are had nothing in common with each other, and make troubles for different uses.

Summary of the invention

For overcoming in the prior art, use the semiconductor memory card of FLASH flash memory, the inconvenience that outer enclosure and interface type of attachment bring for different uses, the utility model design a kind of semiconductor memory card outer enclosure and interface type of attachment to overcome the deficiencies in the prior art.

The technical scheme in the invention for solving the technical problem is: semiconductor memory card is by the storage card housing, flash memory, storer control chip and flash memory and storer control chip interface circuit are formed, flash memory, storer control chip and flash memory and storer control chip interface circuit are encapsulated in the rectangle storage card housing, on the card storage housing, be provided with one group of contact chip that is connected with control chip and piece together pin, the contact chip pieces together in the pin, pieces together pin and puts in order and be the MC1 data line interface, the MC0 data line interface, the GND interface of the ground wire, MC-CLK clock line interface, the VDD electric source line interface, the reserved data line interface, the reserved data line interface, the GND interface of the ground wire, M2 order wire interface, the MC3 data line interface, the MC2 data line interface.

The beneficial effects of the utility model are, storage card outward appearance volume is little, the utility model embodiment minimum volume can reach length * wide * height and be of a size of, 18mm * 12.4mm * 1.4mm, easy to carry, processing technology is simple, enhances productivity, improve the finished product acceptance rate, bring convenience to use simultaneously.
