Title: Semiconductor memory device with flash write mode of operation
IPC: G11C7/10
Filed: 1989-07-14
Abstract: A semiconductor memory device according to the present 
invention has a flash write mode of operation as well as a usual 
single bit write mode of operation, and a flash write switch 
circuit is provided between a flash write data bus system and 
parts of data bit lines for concurrently transferring a flash 
write data bit to the parts of the bit lines prior to activating 
sense amplifier circuit coupled to the bit lines, so that flash 
write data bus system merely needs to swing the parts of the bit 
lines within a relatively small range, thereby allowing a driver 
circuit coupled to the flash write data bus system to be de­
creased in size.

Title: Method and apparatus for recording and reproducing information including plural channel audio signals
IPC: H04N21/432
Filed: 1989-07-27
Abstract: A method for recording and reproducing information 
including plural channel audio signals on and from a 
recording medium. A sampling operation at a predetermined 
sampling frequency is respectively performed against 
plural channel audio signals, a modulation operation of a 
predetermined modulation system is performed respectively 
for each of a plurality of channels of the sampled data, 
an identification code identifying each channel is added 
to each of plural channel coded information signals, and 
subsequently the coded information signals are 
multiplexed by a time division multiplexing operation and 
recorded on the recording medium together with one 
channel analog audio signal or by themselves. At the time 
of play-back, at least two of the plural channel coded 
information signals designated by a selection command or 
at least two of the plural channel coded information 
signals and the one channel analog audio signal 
designated by the selection command selectively decoded 
arbitrarily using the identification code, and a 
reproduction signal is generated by mixing the at least 
two channels of audio signal. With this feature, a single 
disc can be used for recording a program having 
multilingual audio signals.
Patent EP-0355641-A3 (EP)
IPC: B29C43/40
Filed: 1989-08-12
Abstract: A molded bonded fibrous sheet is completely sealed in a 
facing sheet during the molding operation. A fibrous layer 
containing uncured binder is placed in a mold. Facing sheets 
covering the major faces of the layer are included. Under the 
application of heat and pressure the mold faces form the layer into 
the desired shape and thickness, while at the same time the cover 
sheets and fibrous layer are trimmed by cutting edges. A shoulder 
connecting the cutting edge of one of the molds to the mold face 
forces the adjacent sheet into contact with the other sheet, and the 
cured binder seals the sheets to each other and to the severed edge 
of the fibrous layer, thereby encapsulating the fibrous layer within 
the cover sheets. A similar arrangement can be utilized in 
connection with a press to adhesively apply a facing sheet to the 
body and edge portion of a previously formed substrate.

Title: Nonvolatile semiconductor memory device capable of preventing read error caused by overerase state
IPC: H01L27/115
Filed: 1989-12-28
Abstract: A non-volatile semiconductor memory device includes 
a voltage supply circuit (14) for supplying a positive 
voltage (Vcs) to the source line (SL1, SL2, ...) or bit 
line (BL1 to BLn) to which a low biasing voltage is 
applied with respect to each of non-volatile memory 
cells (MC11 to MCmn) in a memory cell array (MCA) in a 
data read mode. Since this voltage supply circuit (14) 
applies the positive voltage to the memory cells (MC11 
to MCmn) in the data read mode, an effect equivalent to 
a back gate biasing effect to the memory cells (MC11 to 
MCmn) can be achieved. When the memory cell (MC) in an 
overerase state is present, the threshold voltage of 
this memory cell (MC) is substantially shifted to a pos­
itive value in the data read mode.
