Abstract
Disclosed are a universal serial bus (USB) memory device having a 5 pin USB connector which may be directly used for a portable terminal and a method of manufacturing the same. The USB memory device includes: at least one 5 pin USB connector; a memory to write data received from the 5 pin USB connector or reading out stored data to transmit the data to the 5 pin USB connector; and a controller electrically connected to the 5 pin USB connector and the memory to control data transmission between the 5 pin USB connector and the memory, wherein the 5 pin USB connector comprises a power terminal, a ground terminal, a D+ terminal, a D− terminal, and an ID terminal, and the ID terminal is connected to the ground terminal so that the 5 pin USB connector is grounded.
Claims8
A universal serial bus (USB) memory device comprising:
- at least one 5 pin USB connector;
- a memory to write data received from the 5 pin USB connector or reading out stored data to transmit the data to the 5 pin USB connector;
- and
- a controller electrically connected to the 5 pin USB connector and the memory to control data transmission between the 5 pin USB connector and the memory,
- wherein the 5 pin USB connector comprises a power terminal, a ground terminal, a D+ terminal, a D− terminal, and an ID terminal, and the ID terminal is connected to the ground terminal so that the 5 pin USB connector is grounded.
A method of manufacturing a universal serial bus (USB) memory device, the method comprising:
- forming a 5 pin USB connector including a power terminal transferring VCC power, a ground terminal transferring a ground signal, a D+ terminal and a D− terminal transferring a data signal, and an ID terminal selectively transferring a client signal and a host signal to an external device, and transferring a signal in such a manner that an external device connected to the 5 pin USB connector is recognized as a client when the ID terminal is connected to the ground terminal so that the 5 pin USB connector is open without being connected to a mobile terminal, and transferring a signal in such a manner that the external device connected to the 5 pin USB connector is recognized as a host when the 5 pin USB connector is shorted with the mobile terminal;
- forming a controller configured to manage data input/output of the memory while controlling an operating system of the portable terminal connected to the 5 pin USB connector to recognize a USB memory device, and electrically connected to the 5 pin USB connector and the memory to controls data transmission between the 5 pin USB connector and the memory;
- forming a memory configured to write data from the 5 pin USB connector or read out stored data to transmit the data to the 5 pin USB connector, freely store or delete data and maintain the data even if power is turned off.
