Title: Trunk card
Inventor: KIM JEONG GYU
IPC: H04L12/50
Filed: 1998-12-24
Abstract: PURPOSE: A trunk card is provided to utilize a T1 or E1 trunk in a corresponding one trunk card. CONSTITUTION: A trunk card comprises the devices as follows. A controller(25) performs a selection of an E1 mode or T1 mode, and a selection control and a state management of a reference clock. Many framers/transceivers(21-1/21-N) perform an each trunk interface and a framer function, by initializing an internal resistor according to control of the controller and generating an interrupt service routine corresponding to a T1 mode or an E1 mode. Two E1 multiplexers(22-1,2) select a reference clock for synchronization among clocks extracted from an E1 mode trunk, through the respective framers/transceivers according to control of the controller. Two T1 multiplexers(22-3,4) select a reference clock for synchronization among clocks extracted from a T1 mode trunk, through the respective framers/transceivers according to control of the controller. An E1 synchronizing unit(23-1) generates a system clock by being phase-locked to a reference clock selected in the E1 multiplexers according to control of the controller. A T1 synchronizing unit(23-2) generates a system clock by being phase-locked to a reference clock selected in the T1 multiplexers according to control of the controller. A multiplexer(24) selects one system clock synchronized to a trunk in a good state among system clocks of the E1 and T1 synchronizing units, according to control of the controller.

Title: Circuit for verifying over erase of repair fuse cell
Inventor: KWON O WON
IPC: G11C16/34
Filed: 1998-12-28
Abstract: PURPOSE: A circuit is provided to verify the over erase of a repair fuse cell as well as to adjust the threshold voltage of a cell for a low level. CONSTITUTION: A first NMOS transistor(N51) is turned off by a fuse cell selecting signal(TCSEL) of low state for preventing an address signal(ADDS) from being fed to the drain terminal of a fuse cell(M2). A second NMOS transistor(N52) is turn on by a reset signal(RSTb) in a High state. A third NMOS transistor(N53) is turned on by a reference voltage(VREF) of high state. Thus, 0V is fed to the gate terminal of the fuse cell. If the fuse cell is over erased, electric current is flowing for the potential of a first node(Q51) to maintain low state. The potential of the first node is inverted via a first inverter(I51) of a latch circuit(21) for a second node(Q52) to be a high state. The signal is inverted into low state via a third inverter(I53) for being fed to first and second transferring gates(T1,T2). The second transferring gate is turned on by the high state of fuse cell verifying signal(TCAMVERIFYr). And, the potential of low state is fed to an NOR gate(NOR2). The NOR gate receives the states of each cell. When the NOR gate receives at least one high state signal, an output of low state is fed to an input/output pad(31). Thus, a proper erase is verified.

Abstract: PURPOSE: An apparatus for repeating characters of a smart card interface using a universal asynchronous receiver transmitter(UART) is provided to reduce character transmitting time by sensing an error signal of a guard time section to decide whether same characters have to be retransmitted when the characters of the smart card interface are transmitted, and to improve transmission efficiency by storing retransmitting character data in the smart card interface. CONSTITUTION: An apparatus for repeating characters of a smart card interface using a universal asynchronous receiver transmitter(UART), comprises an error signal generator(20), a first AND gate(21), a buffer(22), an error signal detector(23), a second AND gate(24), a shift register(25), and a multiplexer(26). If a signal is inputted from the UART displaying parity errors of receiving data when characters are received from a smart card, the error signal generator generates parity error signals in a guard time section. The first AND gate receives a serial signal of the UART and a signal of the error signal generator, and applies an AND operation. The buffer applies an output of the first AND gate by a serial enable signal. The error signal detector detects whether the parity error signals are generated from the smart card when the characters are transmitted with the smart card, and outputs an error signal or a next character enable signal or a character repeating enable signal. The second AND gate receives a mask signal for intercepting a signal inputted to the UART in an unnecessary section, and receives a signal output from a serial input/output terminal to apply the AND operation. The shift register temporarily stores character data of the UART. The multiplexer selects one of the character data and an output of the shift register, by the character repeating enable signal.
