Flash memory, whether embedded or removable, is at the core of the consumer electronics revolution. Every mobile phone, MP3, PMP player, PDA, memory card and USB Flash Drive on the market today has massive amounts of memory, either embedded or by means of expansion slots, adding to the device’s value. |
|
Flash memory has become an integral part of mobile life |
|

|
|
|
| |
As the market size of digital consumer products and mobile phones grows, so will the demand for Flash memory. According to IDC, CAGR for Flash memory cards and USB Flash drives is estimated at 38%, with more than 660 million units shipped in 2007 and 1.5 billion by 2010. |

Mobile devices will be the largest consumers of Flash storage capacity |
|
| |
|
|
|
| |
Security has paved the way for Flash memory into the mobile phone industry by providing the necessary foundation to enable new applications such as Digital Rights Management (DRM), secure storage, enterprise applications, device management, SIM Lock and commerce. |

As a consumer electronics application, the overall bill-of-materials must meet the price points prevalent in the market. Flash memory is also being applied to high performance applications such as video and audio where the user experience is crucial. Finally, above and beyond functionality, a security solution must deploy state-of-the-art countermeasures to combat hackers and malicious attacks. |

Removable Flash memory acts as an effective mechanism for extending the capacity of the device without increasing handset costs. The security feature serves as a protection mechanism against lost or theft of corporate or personal data. Security (as part of a content management scheme) plays a pivotal role when it comes to protection of proprietary third party content such as audio and video clips.
Mobile phones will account for 87% of memory cards shipped in 2010, up from 64% in 2007. (IDC, May 2006)

Device-Card interaction is also significantly enhanced by the presence of a security solution. Today’s fully functional mobile devices, combined with security enabled Flash memory, ensure that data can be securely passed between the card and the device, enabling the safe usage of external data, a key requirement for content portability. With security on the Flash card, the device and card can also authenticate one another, ensuring the proper use of proprietary data and acting as an effective mechanism against handset theft. |

High Capacity SIM

The increased multimedia capability of medium to high-end handsets runs in stark contrast to their storage capacity. This creates an imbalance between the content that can be created and used by a subscriber and the handset's ability to store that content.
Digital cameras, high quality audio and color displays have become standard in today's mobile phones. These features all have a common requirement - storage. High Capacity SIM (HCS) offers a secure, cost-effective means to address the storage requirements of enhanced multimedia handsets, combining the storage capacity of a secure digital or multimedia card (typically 256 MB) with smartcard functionality. HCS conforms to the physical dimension of the SIM Card, does not require an additional expansion slot and can provide a high capacity solution to any SIM card-enabled handset.

Removable Flash storage has also been applied effectively to the personal computing market, in the form of USB Flash drives. These devices provide more than just storage: They act as convenient, quick and cost-effective mechanisms to access files and applications from any personal computer, while security plays a vital role in protecting valuable data and applications from loss and theft.

|
USB drives have become important business tools that require security |

The combination of storage and security opens a new range of authentication applications. Enterprises can now store “unlimited” data about an individual and match that data using a proven authentication scheme. This means governments can store rich biometric and historical travel records, health care organizations can store complete medical histories and businesses can store transactions histories, all in a secure environment, coupled with the ability to authenticate the card holder.

Together, storage and security open a new range of authentication applications |
