New structure? Wasn't aware they'd done that - or maybe you're not talking about separating/spinning off the Imaging/Optics division?
As far as the new chips, another one out today, perhaps the 2nd one you mention:

Invensas Validates DFD-Based RDIMM Modules With Montage Chips
SAN JOSE, Calif., Sep 14, 2011 (BUSINESS WIRE) -- Invensas Corporation, a wholly owned subsidiary of Tessera Technologies, Inc. has validated high performance DDR3 registered dual inline memory modules (RDIMMs) incorporating its dual face down (DFD) packaging technology with Montage Technology's advanced register M88SSTE32882-H0 clock driver chip.
DFD is a dual die implementation of Invensas' multi-face down (xFD(TM)) packaging technology platform. xFD technology meets data center server DRAM requirements by delivering a denser, faster, more cost-effective packaging solution which can be produced using existing manufacturing processes. In addition, a 20 to 30 percent reduction in thickness and a thermal transfer improvement of 20 to 30 percent provides an optimized platform for a range of DRAM memory modules.
