Patent JP-H0461381-A (JP)
Title: Non-volatile semiconductor memory and manufacture method
Inventor: FUKUMOTO KOTA
IPC: H01L21/336
Filed: 1990-06-29
Abstract: PURPOSE:To make it possible to write in electrons from a source in a more simplified manner by increasing the surface concentration of an offset region in terms of a surface concentration of the lower part of a floating gate out of a channel region and compensating for a portion of shortage by a capacity coupling through a control gate from a third gate electrode. CONSTITUTION:A drain region 6 is overlapped in a region S in terms of floating gates 3 and 21 while an offset region between a source region 7 and the floating gates 3 and 21 is the same type with that of a substrate 1 and it is a region whose concentration is greater than that of a surface section 1a of the substrate 1 which excludes the offset region. In order to reduce a cell area, third gate electrodes 12 and 23 are capacity-coupled with the floating gates 3 and 21 at a location where control gates 9 and 22 are lapped. Out of the potentiality of the floating gates required to implant electrons from the source 7, the rest of the potentiality deducted by a portion of the potentiality provided from the control gates 9 and 22 is made up for by the third gate electrode 23 which is indirectly capacity-coupled with the floating gates 3 and 21 through the control gates 9 and 22, which makes it possible to write in a stable manner.

IPC: H04L29/08
Filed: 1989-07-05
Abstract: PURPOSE:To improve the communication efficiency by measuring the frequency of receiving a retransmission request frame caused by the deteriorated state of a communication line and setting the speed of data transmission in response thereto. CONSTITUTION:Upon the receipt of a command of a data transmission speed, a communication controller main body 1 changes the data transmission speed to a line via a line connection line 4 and reports it to a retransmission frequency measuring circuit 2 upon the receipt of a retransmission request frame from the line via the line connection line 4. The retransmission frequency measuring circuit 2 detects the deteriorated communication state depending on the reception number of the retransmission request frame within a prescribed time and reports it to a speed command circuit 3. The speed command circuit 3 discriminates how much the data transmission speed is to be decreased depending on the state of the frequency of the retransmission to command the data transmission speed to the communication controller main body 1. Thus, the communication speed not causing the retransmission is always set depending on the change in the communication state and the data communication with a maximum efficiency is always implemented.

Title: Automatic adjusting circuit for reference voltage of comparator
Inventor: KIKUCHI MASAHIRO
IPC: H03K5/08
Filed: 1981-10-30
Abstract: PURPOSE:To prevent a comparator from being not in operation and malfunctioning owing to a noise, by smoothing an input signal to the comparator and then obtaining a reference voltage through voltage division. CONSTITUTION:Part of an input signal to a comparator A is inputted to an integration circuit B through a diode D for stopping a reverse current.
