    Abstract: A fabrication method and resultant three-dimensional multichip package having a densely stacked array of semiconductor chips interconnected at least partially by means of a plurality of metallized trenches are disclosed. The fabrication method includes providing an integrated circuit chip (50) having high aspect ratio metallized trenches (62) therein extending from a first surface to a second surface (58) thereof. An etch stop layer is provided proximate the termination position of the metallized trenches with the semiconductor substrate (52). Next the integrated circuit device is affixed to a carrier (70) such that the surface of the supporting substrate is exposed and substrate is thinned from the integrated circuit device until exposing at least some of the plurality of metallized trenches therein. Electrical contact can thus be made to the active layer of the integrated circuit chip via the exposed metallized trenches (66). Specific details of the fabrication method and the resultant multichip package are set forth.

    Abstract: In a memory system comprising a plurality of memory units (10) each of which possesses unit-level error correction capabilities (20) and each of which are tied to a system level error correction function (30), memory reliability is enhanced by providing means for fixing the output of one of the memory units at a fixed value in response to the occurrence of an uncorrectable error in one of the memory units. This counter-intuitive approach to the generation of forced hard errors nonetheless enhances overall memory system reliability since it enables the employment of the complement/recomplement algorithm which depends upon the presence of reproducible errors for proper operation. Thus, chip level error correction systems, which are increasingly desirable at high packaging densities, are employed in a way which does not interfere with system level error correction methods.

    Abstract: The non-volatile semiconductor memory includes a one device dynamic volatile memory cell having a storage capacitor (C5) with a plate (12) and a storage node (10) coupled to a non-volatile device having a floating gate (FG), a control gate (24) and a voltage divider (16) having first and second serially-connected capacitors (C1, C2), with the floating gate (FG) being disposed at the common point between the first and second capacitors. The plate (12) of the storage capacitor is connected to a reference voltage source. The control gate (24) is preferably capacitively coupled to the floating gate (FG) through the first (C1) capacitor which includes a dual charge or electron injector structure (26). The capacitance of the first capacitor (C1) has a value substantially less than that of the second capacitor (C2).

    Abstract: A high speed ratioless FET sense amplifier for sensing stored information in a semiconductor memory system. The amplifier is capable of sensing very small voltage signals provided by charges stored in a plurality of single FET/capacitor memory cells. The amplifier comprises a pair of cross-coupled FET devices coupled to a pair of bit/sense lines by clock signal responsive switching devices. The source electrodes of the cross-coupled FETs are each independently capacitively coupled to another clock signal and also to a source of low potential through a pair of clock driven source pull-down FETs. The amplifier uses minimal size devices and is process parameter independent.
