Samsung Ships First Multi-chip Package with a PRAM Chip for Handsets

Apr 28, 2010

Samsung Electronics today announced the industry's first multi-chip package (MCP) with PRAM - for use in mobile handsets, beginning later this quarter

The 512 megabit Samsung PRAM in the MCP is backward compatible with 40 nanometer-class* NOR flash memory in both its hardware and software functionality, allowing mobile handset designers the convenience of having multi-chip packaging fully compatible with past stand-alone PRAM chip technology. PRAM is expected to be widely embraced by next year as the successor to NOR flash in consumer electronics designs to become a major .

“Memories for portable consumer devices today are at a major turning point as mobile applications increasingly require more diverse memory technologies,“ said Dong-soo Jun, executive vice president, Memory Sales and Marketing, . “The launch of our PRAM in an advanced MCP solution for the replacement of 40nm-class and finer geometry NOR meets this need head-on. Our PRAM MCP will not only enable handset designers to utilize conventional platforms, but expedite the introduction of LPDDR2 DRAM and next-generation PRAM technology as the leading-edge basis for high-performance solutions,” he added.

PRAM, which stores data via the phase change characteristics of its base material, an alloy of germanium, antimony and titanium, provides three-times faster data storage performance per word than NOR chips. This new PRAM-packaged memory combines the nonvolatile nature of flash memory with the high-speed capability of DRAM. Its simple cell structure makes designing MCP chips for handsets a faster and easier process, with the imminent use of 30nm-class and finer process node technology to overcome long-time design difficulties inherent in NOR flash technology.

As a replacement for NOR, PRAM can more easily accommodate the growing demand for high-speed, high-density nonvolatile memory in mobile phones and other mobile applications such as MP3 players, personal multimedia players and navigational devices.

Samsung is continuing its research and development into PRAM and other advanced memory chips to enable faster ‘write’ capabilities, a key feature in taking photo images, providing multimedia messaging and recording video clips to reduce the standby time in data storage. This high-speed write capability will be important in a diverse span of digital storage and consumer devices, such as solid state drives (SSDs) and HDTVs.

Samsung made the correction of replacing "titanium" with "tellurium", but it shows that they can be careless with their announcements. This is not their first 512 Mb PRAM announcement either.

The resistance and Vth distribution in a large array will become very wide after some use. Numonyx released it early because Micron was about to buy them, and there's less chance for a release after the acquisition. Samsung is not in the same rush, it has been announcing this for four years apparently.
