Title: Process for preparing bis (ether anhydrides) using alkylamine derived bisimides having low melting temperatures
Inventor: DELLACOLETTA BRENT ALLEN
IPC: C07D209/48
Filed: 1995-04-28
Granted: 2000-07-21
Abstract: A process for making bis (ether anhydrides) employs alkylamines having low melting temperatures thus allowing for novel intermediate process steps for preparing bis (ether anhydrides). The alkylamines have alkyl groups which contain at least three carbon atoms and have boiling temperatures in the range of 48 to 250 DEG C at atmospheric pressure. As a result of using these amines, liquid alkylamines now can be employed in the imidization process step. The N-alkyl nitrophthalimides prepared from the recovered imidization product according to this invention can now be purified using liquid/liquid extraction or vacuum distillation. The alkyl nitrophthalimides prepared according to this invention provide for displacement reactions which now can be run at a high solids level. Likewise, the exchange reaction can be run at a higher solids level, and thus achieves an efficiency level which is higher than conventional processes.

Title: Dual-bank memory module with shared capacitors and R-C elements integrated into the module substrate
Inventor: CHU TZU-YIH
IPC: G11C8/12
Filed: 1997-10-30
Granted: 2000-04-11
Abstract: A memory module has DRAM chips mounted on both a front and a back surface but decoupling capacitors mounted on only the front surface. Each decoupling capacitor is for suppressing current spikes from a pair of DRAM chips. The pair of DRAM chips includes a first DRAM chip on the same surface as the capacitor and a second DRAM chip opposite the first DRAM chip on the back surface of the module. The first DRAM chip belongs to a first bank while the second DRAM chip belongs to a second bank. Two RAS signals are for controlling access to the two banks. Since only one bank is accessed at any time, and access causes current spikes, only one bank and only one DRAM chip in the pair of DRAM chips creates a current spike at any time. Thus a capacitor can be shared between the two DRAM chips in the pair. The shared capacitor can be mounted next to or under one of the DRAM chips, or formed within the multi-layer substrate itself. Having capacitors on only one of the surfaces reduces the number of placement sequences required, reducing manufacturing cost.
