Abstract: PURPOSE: A method for performing location registrations in a wireless local loop(WLL) is provided to make many radio interface units(RIUs) periodically transmit location registering messages by using different optional cycles to reduce amounts of the messages, so as to minimize system load of the WLL. CONSTITUTION: A radio interface unit(RIU) drives a timer for periodically performing location registrations. The RIU inputs a cycle relating to the location registrations from a radio port operation and maintenance system(RPOM). The RIU inputs a random number value from a random number generator. The random number generator sequentially generates random numbers statistically having regular distributions within a regular time. The RIU adds a location registration value to the random number value. The RIU compares the added value with a time value measured by the timer. If the time value is bigger than the added value, the RIU transmits a location registration request to a radio port controller(RPC) through a radio port unit. If the time value is not bigger, the RIU stands by until the added value is bigger than the time value.

CONSTITUTION: In a ferroelectric random access memory(FRAM), a first transistor(T1) is a ferroelecric NMOS transistor with a ferroelectric insulation surface. Second and third transistors(T2,T3) have each a normal insulation surface. In the write mode, a wordline(W/L) activates from LOW to HIGH, activating the second and third transistors(T2,T3). Thereby a critical voltage above ferroelectric polarization is given between a section line(SL) and a control line(CL). Thus the critical voltage is transmitted to the source nodes(N1,N2) of the second and third transistors(T2,T3). The voltage of the node(N1) is given to the source and substrate of the third transistor(T1). The voltage of the node(N2) is given to the gate of the first transistor(T1). Thus the direction of the polarization of the ferroelectric substrate in the first transistor(T1) is determined by the voltage of the gate and substrate. If the substrate voltage is higher than the gate voltage, logic zero("0") is stored. In the opposite case, logic high("1") is stored.

Abstract: PURPOSE: A method for suppressing current consumption of a terminal is provided to set up a predetermined limit time even in a call waiting state or a reception standby state of the terminal, and to turn off power of an LCD(Liquid Crystal Display) window even when a user does not call until the set limit time or a call is not generated from other terminal. Therefore, unnecessary current consumption is suppressed. CONSTITUTION: If a user turns on terminal power(S41), an LCD(Liquid Crystal Display) window is displayed(S42). A terminal waits a keypad inputting in a call waiting state or a reception standby state(S43). If the user presses a key input button, an LED(Light Emitting Diode) is turned on(S44). If a 'call' button is pressed, a connection progresses to form a speech channel between the terminal and a base station(S45). A user detection unit senses whether the user speaks on the phone(S46). The user detection unit decides whether the user continues the call over a predetermined limit time(S47). If so, the user detection unit intercepts power supplied to the LCD window through a control circuit(S48). If the LED is turned on/off by a time difference at a high speed, which a human time does not recognize, brightness of the LED is easily controlled by an afterimage effect, because the human time can not recognize a turning-off(S49). The user's call is completed(S50).
