T-Flash is the smallest removable Flash storage for mobile phones
Posted on 27-Feb-2004 18:18. | Tags Filed under: News.

SanDisk T-Flash is currently the world's smallest removable flash memory storage format. It is similar in size and function to embedded flash memory but can also be readily removed and upgraded to allow for a range of memory capacities as well as interoperability with other consumer electronics devices. Approximately the size of a fingernail, T-Flash is designed for new mobile phones that are compact yet fully-featured with storage-intensive multimedia applications such as digital cameras, video capture and playback, MP3 players, video games, personal organizers, Multimedia Message Service (MMS), email and voicemail capabilities.

The small size of T-Flash (11mm x 15mm x1mm) represents approximately one quarter of the volume of the smallest removable flash cards available on the market today. T-Flash uses advanced packaging technology and SanDisk's latest NAND MLC flash memory and controller technologies.

Motorola announced at the 3GSM Congress in Cannes, France, the Motorola E1000 and the Motorola A1000, two 3G phones that will use the 32MB T-Flash. These two phones are expected to be available in the second half of this year.

T-Flash is designed to store personal content such as digital images, MP3 music files, video games and other applications, phone settings and personal data. Due to its very small size and substantial storage capacity, it is likely to remain in the handset for extended periods; however, it can easily be removed and inserted into another phone when consumers want to upgrade their phones.

This usage model is similar to the SIM (Subscriber Identity Module) cards used in most mobile phones worldwide that can be transported by the subscriber from one handset to another. However, SIM cards have very limited flash memory storage and suffer from a very slow data transfer rate that is not suitable for tens or hundreds of megabytes stored. T-Flash has approximately half the footprint of SIM cards.

When inserted into an available SD adapter, T-Flash converts into the SD card for interoperability with standard SD devices so consumers can exchange data between their T-Flash-equipped mobile phone and any SD compatible host, such as a digital camera, PDA or laptop PC.

Due to its ability to store operating system code and system data, T-Flash offers mobile phone manufacturers and network operators the flexibility to offer customized memory configurations, additional software and applications upgrades. In addition, service providers can create custom carrier bundles that are tightly integrated with handsets and stored on T-Flash so they can be easily replaced or upgraded in the field.

Volume production is expected to commence in the second quarter. Pricing ranges from US$14 to US$39 for capacities that range from 32MB to 128MB.
