    Supertechina (Shanghai) Electronic Co., Ltd. developed smallest UDP USB flash drive on April 10, 2009.
    Chip on Board Flash Memory
    COB, or chip on board for short, is a type of flash memory that can actually look very similar to either of the two other types of flash drives. What makes COB different than a traditional flash drive for example is that instead of having the controller chip and flash memory chip separate, on a COB both the controller and the flash memory are built together. This combined structure actually gives a COB flash drive a slight performance boost than traditional memory.

    Within COB memory, there is also a style called thin COB. Thin COB can be placed in many USB flash drive housing that are too small for traditional or COB chips. It is much smaller and can actually be found in some of the smallest USB drives on the market. This does not mean, however, that all small USB drives are made from COB chips; some are made from UDF chips discussed below.

    COB memory is the least expensive option to produce and was brought around to fulfill the need of making cheaper flash rives. In terms of durability, ironically this less expensive drive is actually a little bit more durable. However, unlike the traditional style, a COB flash drive cannot be repaired if damaged. For example: if you were to receive a traditional flash drive, and a component broke on the drive. Then it would be possible to send the USB drive back to the manufacture for repair. On a COB drive however, this is not possible due to how they are manufactured.

    UDP Flash Memory
    UDP memory is widely considered to be the smallest of the small. UDP is primarily used in extremely small USB drives and is the most rugged form a USB can come in. This is because much like a COB chip, the controller chip and memory chip are built together. However, unlike a COB drive, UDP flash drives have all the components built together in a single solid piece.

    This solid piece makes the UDP extremely durable, shock resistant, as well as waterproof! This does not mean however that they are indestructible; it just means that it is more resilient to damage than the other types of memory.

    Unfortunately UDP memory is the most expensive of the three types; with COB being the cheapest, followed by traditional in second. Although it is slightly more expensive, it is still in the reasonable range for the majority of consumers and many of them don’t even know they have purchased a UDP chip to begin with.

    Flash memory has come a long way since it was first released, and now with millions of devices on the market with billions of product combination’s, it truly is amazing how wondrous it has become.
