Found this to be interesting. Something CPQ could get into as well?? Not having much of a technical background I'm not sure.
Military specialist touts stacked-DRAM modules -- Dense-Pac going commercial
By Ron Wilson
Garden Grove, Calif. - Armed with a new chief executive and a unique packaging capability, Dense-Pac Microsystems Inc. is moving beyond its military electronics niche to look for commercial customers. "Our job now is to let designers know that we are a cost-effective alternative for any kind of commercial system where space is at a premium," said Uri Levy, the company's new chairman and chief executive.
Dense-Pac's specialty is the stacking of DRAMs. It has a wide range of memory modules that consist of thin-packed DRAMs stacked one atop the other. The resulting stack has the same footprint and pin-out as a single DRAM-except for separate chip-enable signals-but with the capacity of many chips, not one.
For years the company has marketed its modules to the military airborne and ground-vehicle markets. But as the company needs to grow and the military now needs to shrink, Dense-Pac has turned to other markets. Obvious applications are handheld systems, automotive systems and other such areas where board area is a vital statistic.
But the move to the commercial world required some adjustments.
"When I came here there was no system for mass production of our modules," Levy said. "There wasn't even a data book engineers could use to specify our components."
Production technique
Levy has set about reorienting the technically strong company to the commercial world. He has helped produce a CD-ROM data book, revamp the company's Web site and fund the development of a production technique for the company's stacked packaging.
The moves have already brought in at least one new account. IBM Corp.'s System 390 desktop group is supplying IBM-made DRAMs to Dense-Pac for repackaging; IBM then assembles the stacked devices into 1-Gbyte plug-in memory boards.
In other commercial oppor-tunities, Dense-Pac is aiming stacked SRAM/ROM combinations and SRAM/flash combinations to such applications as cellular handsets and digital cameras.
In the future, the company expects to move beyond memory, Levy said. IBM has expressed interest in stacking CPUs in ball-grid arrays for a multiprocessing application, so Dense-Pac is working out the technology to stack high-I/O chips with dissimilar pin-outs. This could produce-if power dissipation permits-a stacked component that includes CPU, memory and peripherals for an embedded processor, all within the footprint of a single chip. |
