Title: Non-volatile semiconductor storage device and its manufacturing method
Inventor: TANIMOTO MASAO
IPC: H01L21/8247
Filed: 1996-08-08
Abstract: PROBLEM TO BE SOLVED: To readied resistance of a part where a memory transistor is formed and to suppress snapback phenomenon by, in a semiconductor substrate, forming a memory transistor forming area where impurity concentration is higher than the semiconductor substrate. SOLUTION: Relating to an EEPROM, a P-type well 4 separated from a substrate 1 is provided in an N-type well 2, and an N-type transistor formed in the P-type well 4 is contained. Thus, for example, at wiring data or erasing it, a structure wherein electric potential of both polarity, positive electric potential and negative electric potential, can be used is obtained. In addition, a memory cell transistor is formed in a P<+> type memory transistor forming area 3 which is higher in impurity concentration than the substrate 1. Thereby, while snapback phenomenon is suppressed, finer constitution of the memory transistor becomes possible, since the resistance of the P<+> type memory transistor forming area 3 decreases.

Title: Rush current limiting circuit
Inventor: NODA HIROSHI
IPC: H02H7/12
Filed: 1996-08-08
Abstract: PROBLEM TO BE SOLVED: To improve the efficiency of a rush current limiting circuit for switching regulator. SOLUTION: When a switch 23 is closed, a capacitor 26 is charged from a rectifier 24 through a resistor 25. When the capacitor 26 is charged, NMOSs 28 and 35 are maintained in turned-off states. Thin a drive circuit 29 starts the switching of the NMOS 28 and, when the NMOS 28 is maintained in a turned-on state, exciting energy is stored in a transformer 27. When the NMOS 28 is turned off, the transformer 27 discharges the exciting energy and a flyback voltage is generated in a winding 27a. Therefore, the voltage S28 at the drain D of the NMOS 28 becomes the sum of the voltage V26 of the capacitor 26 and the flyback voltage VF. A voltage having the equal value to that of the flyback voltage VF is stored in a capacitor 31.  The flyback voltage VF stored in the capacitor 31 is supplied to the gate G of the NMOS 35 after the voltage is damped by means of a resistor 33 and a Zener diode 34. When the voltage VF is supplied to the gate G, the NMOS 35 is turned on and the resistor 25 is short-circuited, resulting in the operation of a switching regulator.

Filed: 1989-08-16
Abstract: PURPOSE:To prevent interception by using 1st and 2nd cryptographic keys to access a caller station and a called station with a base station separately and allowing the base station to connect the caller station and the called station when verification is confirmed, thereby setting a 3rd cryptographic key between both stations. CONSTITUTION:A caller slave station (not shown) requests access to an access management information storage section 16 of a base station via a transmission line L1. A cryptographic coding section 12 fetches a random number from a specific random number generator 13 from a terminal 14 and sends a signal subjected to cryptographic processing to the transmission line L1 to attain the cryptographic processing with the caller slave station. Then the base station applies similar cryptographic processing with the called slave station requested by the caller slave station, sends the resulting signal to a transmission line L2 to apply the cryptographic processing. The transmission lines L1, L2 are connected by a switch 20. Then the caller slave station and the called slave station generate a new cryptographic key to use a random number table inherent to the slave station. Thus, the interception of the communication between slave stations is prevented by the base station.
