UDP Flash Has Driven USB Memory Stick Innovation

When the first USB flash drives hit the market just over 10+ years ago they were all based on one core technological solution and that was the combination of flash memory with a controller chip and a capacitor – these components were soldered onto a printed circuit board and a USB connector provided the interface to the PC. The result was a small(ish), portable and easy to use data storage device – the USB memory stick was born!

The “guts” of the memory stick (the printed circuit board, memory module, capacitor, controller and USB connector) are generally referred to in the industry as a COB solution – think of it as a common engine around which manufacturers build different designs/shells.

In subsequent years the storage capacity of these first generation USB sticks grew from a relatively small 8MB to eventually break through the 1GB barrier. Today memory sticks with a storage capacity of 64GB are common place!

The big shake up in terms of design came with the introduction of the UDP chips – in common with other sectors in the computer and gadget sector what was once achieved on a large COB card could now be achieved on a much smaller form factor. Effectively a UDP chip has the flash memory, the controller and the capacitor all rolled into one and as you can see it’s much smaller.

USB Memory Sticks - COB vs UDP

As a consequence the USB memory stick product designers have had a field day! No longer did their designs have to work with a largish rectangular internal component but instead they could now unleash their creative talents and come up with all sorts of shapes, designs and styles.

Today the market is awash with thousands of different designs ranging from super thin credit cards to tiny little Iron Sticks and lots of really cute custom USB sticks. UDP chips are a boon to designers of Custom USB sticks because pretty much any shape can now be accommodated hence the proliferation of custom USB lips, USB animals, USB truck and cars and USB sticks in the shape of characters from movies.

USB Cards Using UDP Chips

There is no difference in the performance of USB memory sticks that use UDP technology. Their read/writes speeds are just as fast and they’ll support the same number of read/write cycles. Arguably they are more stable because there are no soldered connections to break or weaken over time.
