Hynix to ramp Pseudo SRAM development

Wants 20 per cent of phone memory market

Hynix wants to make further inroads into cellphone memory market, and will begin developing 64MB Pseudo SRAM and NAND Flash memory chips this year targeted specifically at that sector, the company said yesterday.

Mobile handsets have, in the past, typically used Static RAM (SRAM) chips for memory. PSRAM is essentially DRAM technology tweaked to operate like SRAM, but deliver better data throughput rates and lower power consumption - both key requirements for today's increasingly sophisticated handsets.

PSRAM has emerged as SRAM's successor, and almost all of the world's major memory manufacturers are producing now PSRAM parts in order to chase the handset market. Infineon, Micron and Cypress even call the technology cellularRAM; Samsung brands it utRAM. Toshiba rolled out 128Mb PSRAM chips earlier this year.

Hynix claims its PSRAM has now been certified by major overseas manufacturers, though it doesn't name names.

Whether its products have the approval of Nokia, Motorola, Siemens, Sony-Ericsson or a number of them, Hynix still reckons it will be ship $30 million worth of PSRAM parts by the end of the year, taking 20 per cent of the global PSRAM market, the Korea Herald reports. ®
