the type within which the integrated circuit is to 
operate when subsequently mounted thereon. An 
aperture is formed in a hybrid substrate of the 
hybrid circuit in a location where the integrated 
circuit would otherwise be mounted, and a dielec­
tric membrane is clamped over the aperture. Con­
ductive bumps in the underside of the periphery of 
the membrane engage conductors on the upper surface 
of the hybrid substrate surrounding the aperture 
which conductors would normally connect to termi­
nals of the integrated circuit. Conductive bumps 
on the under side of a central area of the membrane 
engage contact areas on the contact face of an 
integrated circuit under test situated therebelow 
and a plurality of conductor runs supported by the 
membrane extend from the conductive bumps in the 
central area of the membrane to the conductive 
bumps in the periphery of the membrane, thereby 
electrically interconnecting the integrated circuit 
under test to the hybrid circuit.

Title: Staggered refresh for dram array
IPC: G11C11/406
Filed: 1988-12-09
Abstract: According to the present invention, each 
successive refresh to the multiple banks of a DRAM 
array is staggered by one clock period. Thus, the 
time required to refresh one row in each DRAM of each 
bank at 10 MHz, for example, is equal to 0.7 µsec., or 
4.4% of the total allowable maximum time between 
refresh cycles. This staggered refresh technique 
avoids large power supply current spikes while 
minimizing the effect on memory access bandwidth.

Title: Digital adaptive filter and method of convergence therein

Filed: 1989-07-20
Abstract: Disclosed is a digital adaptive filter and a 
method of cancelling an echo component generated by a 
partial return of a transmission signal to a receiving 
side. The digital adaptive filter comprises: a main 
memory unit (64) for storing a first echo replica which 
can be stored or read by using the parallel signal from a 
main tap unit (61) as an address signal, at least one 
submemory unit (65) for storing a second echo replica 
which can be stored or read by using the parallel signal 
from a subtap unit (62) as an address signal, and an 
adding circuit (66, 67) for adding the first echo replica 
and the second echo replica. The second echo replica 
stored in the at least one submemory unit (65) has a 
greater precision than the precision of the first echo 
replica stored in the main memory unit (64), and thus the 
accumulated error due to memory division can be reduced. 
Instead of or accompanied by the greater precision, the 
contents of the main memory (64) are updated directly 
based on the error between the pseudo signal and an input 
signal or based on a step size corresponding to the 
error, depending on whether the error is relatively large 
or relatively small, respectively.
