Patent EP-0340891-A3 (EP)
Title: Programmable logic device with programmable word line connections
IPC: H01L21/82
Filed: 1989-02-23
Abstract: A programmable logic device having a 
relatively small number of programmable 
product terms (0E,SETN,INV,P0,P1,P2,ACLK,CLEARN) 
("P-terms") feeding each fixed combinatorial logic 
device (51), and additional "expander" programmable P-terms (EXP1,EXP2) 
which do not directly feed a fixed device. Relatively 
simple logic functions can be performed by suitably 
programming the P-terms feeding the fixed devices. 
More complex logic functions can be performed by 
suitably programming the required number of expander 
P-terms, and then combining the outputs of those 
P-terms by means of another P-term. In order to 
conserve word lines in the programmable array, multi­
plexers (150) allow selection of whether expander outputs 
or external inputs (44) will be applied to certain word 
lines (102).
Patent EP-0359372-A3 (EP)
IPC: G11C29/42
Filed: 1989-07-19
Abstract: A DRAM test system includes a storage location tester and 
controller tester. The storage location tester utilizes an 
error correction code which generates redundancy symbols 
corresponding to inverted data that are the binary inverse or 
compliment of the redundancy symbols corresponding to the non-­
inverted data. Thus each bit-location of an addressable storage 
location, consisting of both data and ECC redundancy bit 
locations, can be fully tested for storage and retrieval of both 
a ONE and a ZERO in only three read/write cycles. The 
controller tester tests the DRAM controller circuitry by 
sequencing it through various operations, at least one of which 
is a refresh operation. When a refresh operation occurs the 
node signals corresponding to the refresh operation are 
incorporated into a DRAM controller signature vector. To 
counter the effects of the refresh operation on the signature 
vector, a refresh-vector is applied to the signature vector 
register during the refresh operation and the contents of the 
register are updated. This results in the contents of the 
signature vector being "returned" to the pre-refresh contents at 
the end of a properly executed refresh. At the completion of 
the testing cycle the signature vector may then be compared with 
the expected output vector, which does not include any refresh 
operation information, to determine if the DRAM is functioning 
properly.
Patent EP-0366453-A3 (EP)
Title: Variable gain current-to-voltage amplifier with gain independent test mode operation
IPC: G01R31/00
Filed: 1989-10-25
Abstract: The present invention provides a testable 
precision variable gain current-to-voltage amplifier 
apparatus which includes an op amp (15) and has a test mode of 
operation wherein the gain is independent of the gain of 
the amplifier when operated in the normal amplification 
mode. The invention enables a test signal, preferably a 
test voltage (Vt), to be injected into the amplifier 
circuit to test the functioning of the op amp (15) and 
thus the amplifier. Because the gain of the amplifier in 
the test mode is independent of the gain of the amplifier 
when in the normal mode, a simple and easy method of 
checking the functioning of the op amp is provided which 
does not require knowing the gain of the amplifier and 
then selecting the proper test input to use.

Title: Method for electrically detecting positional deviation of contact hole in semiconductor device
IPC: H01L21/66
Filed: 1990-02-27
Abstract: A method for detecting a positional deviation of a contact hole 
formed in an interlayer insulator layer includes the steps of forming a 
detection conductor pattern on a substrate at a peripheral portion of a 
contact hole formation area in which a contact hole is to be formed, and 
forming a first insulating layer to cover the detection conductor pattern. 
Then, a first conducting layer of a predetermined pattern is formed on the 
first insulating layer to cover the contact hole formation area, and a 
second insulating layer is formed to cover the first conducting layer. 
Furthermore, a contact hole is formed at the contact hole formation area 
in the second insulating layer, and a second conducting layer is deposited 
on the second insulation layer so that the second conducting layer is 
deposited within the contact hole. Thereafter, a short-circuit between the 
detection conductor pattern and one of the first and second conducting 
layers is detected. When the short-circuit is detected, it is judged that the 
formed contact hole adversely deviates from a proper position where the 
contact hole is to be formed.

Patent EP-0602824-A3 (EP)
Inventor: HUNT CHRISTOPHER J
IPC: G06F13/00
Filed: 1993-12-01
Abstract: In a telecommunications management network including a network
element provisioned as a so-called Directory Services Network Element (DSNE) and
at least one sub-network intended to include one or more network elements,
automatic registration network element identity information is realized by employing
a routing exchange protocol to dynamically maintain identity information of network
elements reachable within the network, enhancing the routing exchange protocol
interface to automatically supply an indication of detection of a newly reachable
network element to an applications layer protocol, and using the indentity
information of a newly reachable network element in the applications layer protocol
of the DSNE to establish communications with the newly reachable network
element. Then, the newly reachable network element supplies additional identity
information (e.g., its name, network address and the like) to the DSNE. The DSNE,
upon receiving the additional identity information, supplies its identity information
to the newly reachable network element. Consequently, the identity information of
the DSNE is supplied to each newly reachable network element as it is added to the
network. This provides all network elements the capability of establishing
communications with the DSNE, so that queries can be made for identity
information of other network elements in the sub-network. The retrieved identity
information can, in turn, be used by the individual network elements to establish
communications with other network elements in the sub-network.

Inventor: HOOGENBOOM CHRIS
IPC: H04N7/50
Filed: 1995-10-13
Abstract: A video syntax parser (40) is provided for a
video decompression processor (20). A compressed
bitstream (106) is examined until a start code (100)
is located. The start code (100) is decoded to
enable a particular parser state corresponding
thereto to be initiated. The parser state is
communicated to a plurality of subsystems (36, 42,
44, 46, 48, 52, 54, 56) of the video decompression
processor (20). Each subsystem monitors the parser
state to determine which parsed data following the
start code, if any, is intended for that subsystem.
The subsystem then retrieves the parsed data it
requires via a data bus (58) which receives the
parsed data from the parser (40).
