SAMSUNG Electronics Unveils 32Mb UtRAM Samples

SEOUL, Korea - February 12, 2001 -Samsung Electronics has completed development of the world's first 32-megabit (32Mb) Uni-transistor random access memory (UtRAM) chip. Company officials have announced that samples of the low power-consuming device have already been shipped to mobile phone manufacturers around the world.

The UtRAM operates on the same low voltage as SRAMs, which are currently installed in mobile handsets. Samsung's new device also has the high data transmission speed of the SRAM. On the other hand, the UtRAM is much less expensive to fabricate. It features a DRAM cell structure with just one transistor and one capacitor whereas the SRAM has six transistors per cell.

Samsung has combined its DRAM and SRAM technologies, which are judged to be among the world's most advanced, to minimize chip power consumption. The UtRAM operates on an active current of 30 milliamperes (mA), a standby current of just 200 microamperes (μM) and only 10 μM in power-down mode.

Samsung's new 32M UtRAM is fully compatible with the SRAMs currently being used in mobile phones. It can replace the SRAM without any circuit alterations in next-generation handsets that require large memory capacity difficult to achieve with SRAMs.

In addition, a tape ball grid array (TBGA) package is used to minimize chip size, helping handset manufacturers to designs models that are smaller and lighter. When needed, a multi-chip package can be used to include a flash memory device with the UtRAM.

With its new product, Samsung aims to lead the market for memory chips used in next-generation mobile phones that can also send and receive email, access online games and perform other such functions. Importantly, Japan is scheduled to begin wide-band CDMA service this coming May, and the handsets for this service will require a memory capacity of at least 30 megabits. Samsung officials believe that this requirement will spur demand for their new 32M UtRAM.

Samsung Electronics has retained the top share of the world SRAM market since 1995. With its latest release, Samsung's SRAM line now includes devices with capacities ranging from one to thirty-two megabits. Samsung expects SRAM sales this year to top US$2.3 billion, and the company plans to have at least 30% of the world SRAM market from 2002.

According to industry analysts, the world mobile phone market will reach some 520 million units this year and will continue to grow about 25% annually. At this rate, one billion mobile phones will be sold per annum by 2004.
