Title: High-speed and low-power 4-T SRAM
Inventor: WANG CHAU-CHIN
IPC: G11C8/00
Filed: 2001-11-01
Granted: 2003-07-01
Abstract: The invention of a CMOS 4-T SRAM is presented. The storage of data is realized by a pair of cross-coupled PMOS transistors, while the wordline controls a pair of NMOS transistors. The problem of weak driving capability of PMOS transistors is revolved such that the 4-T CMOS SRAM becomes a practical design. The wordline voltage compensation circuit and bitline boosting circuit, then, are neither needed to enhance the data retention of memory cells. Built-in self-refreshing paths makes the data retention possible without the appearance of any external refreshing mechanism. Moreover, a pair of quenchers are added between the bitlines in our invention. The quenchers can subside the unwanted oscillation of the bitlines when they are not driven. Hence, the power consumption is reduced. Besides, a cascaded noise-immune ATD (address transition detectors) is also included to filter out the unwanted CS (chip select) glitches when the SRAM is asynchronously operated.

IPC: B81B7/00
Filed: 2002-01-04
Granted: 2003-06-11
Abstract: A method of fabricating a package for a micro-electromechanical systems (MEMS) device. A flex circuit interconnect subassembly for the package is made by placing a flex circuit on a pad insert, attaching a carrier insert to the pad insert to deflect the lead portions of the flex circuit, and applying a cover insert to the pad insert, after the attachment of the carrier insert, to re-deflect the lead portions of the flex circuit toward the device bond sites. The flex circuit interconnect subassembly may be combined with an electronic device die/carrier subassembly to form a completed electronic device package. The flex circuit interconnect subassembly and the die/carrier subassembly are joined using mechanical interlocking layers. The invention is particularly suited for making such an electronic device die/carrier subassembly which has a MEMS die permanently affixed to a carrier. The carrier is advantageously utilized during the process of releasing a protective coating from the surface of the MEMS die which support the various MEMS components. The MEMS components on the MEMS die are hermetically sealed, such as by bonding a cover to the upper package body or the lower package body. The cover may have features such as ports which allow the MEMS components to interact with the external environment.
