Samsung's 2MB Smart Card IC for 3G Phones

Europe France : Samsung Electronics announced the introduction of a 2MB flash memory-embedded smart card IC (S3FJ91L), raising the bar even higher by doubling the data storage capabilities. Samsung's new 2MB smart card IC meets all the industry requirements for 3G multimedia handsets by enabling higher memory density for SMS, telephone directory, games and Internet services as well as its typical subscriber identification function.

The speed and reliability of user identification in the S3FJ91L is guaranteed by ARM-based 32bit SC200 Secure Core, a 3-DES encryption standard and a PKI crypto processor. Its fortified anti-hacking technology significantly reduces the risk of personal information leakage.

Samsung's S3FJ91L IC has a built-in 16KB Static RAM to enable easy upgrades and the introduction of various applications by software developers.

A Java Accelerator also improves the speed and makes it easier to implement Java-based platforms.

The S3FJ91L supports an operating voltage from 1.62V to 5V. Such low power requirement is compatible with power consumption requirements of the GSM standard. In addition, data programming and updating processes operate independently with one another, making memory management easier and more efficient.

For the first time in the smart card industry, Samsung's new IC is manufactured on a 300 mm wafer fab, gaining global competitiveness in terms of cost. The new IC will be applied to various smart cards such as USIM and UIM cards for GSM, GPRS and IMT2000 as well as JAVA and multimedia cards. With the introduction of the new S3FJ91L, Samsung has now established a full line of smart card ICs with embedded memory from 96KB to 2MB.

he market research company, iSuppli, forecasts that the fast-growing smart card market demand will reach 1 billion units this year and surpass 1.6 billion units by 2008.

Reference Data
GPRS (General Packet Radio Service)
Introduced in 1999, this service supports high-speed Internet services and some features of video communication. GPRS is often called 2.5 generation service because it offers technology that falls between the 2G and the 3G or IMT2000.

USIM Card
USIM card for IMT2000 mobile handsets stockpiles subscriber information to support e-commerce, global roaming, digital cash and payment for public transit systems. This card integrates SIM and UIM, which had been preciously operated separately for different mobile services.

3-DES (3-data Encryption Standard)
It refers to an encryption standard released by the US National Institute of Standards and Technology. This standard enhances the security of DES by using three encryption keys.

PKI (Public Key Infrastructure)
PKI utilizes the public key cryptosystem to support authentication of the identification of message senders, encryption of messages and digital signatures. The most widely used PKI is RSA(Rivest Shamir Adleman), an internet encryption and authentication system algorithm which was developed by three mathematicians Rivest, Shamir, and Adleman. A PKI crypto-processor is a system designed to accelerate the RSA operation, the most time-consuming operation for modular exponentiation.
