Title: Circuit for protecting multi-wordline's selection in a memory bank
Inventor: LEE JONG HUN
IPC: G11C7/00
Filed: 2002-05-17
Abstract: PURPOSE: A same bank double-selection preventing circuit is provided to prevent a plurality of word lines from being enabled at the same time in the same memory bank. CONSTITUTION: A synchronous memory device is driven by being synchronized to an external clock signal, and includes at least one memory bank having a structure where memory cells selected by a number of word lines share the same bit line sense amplifier. An active command sensing unit(310) provides an active pulse signal generated as a pulse in response to a bank active command, and provides an active driving signal enabled in response to the generation of the active pulse signal. An active delay(320) provides an active delay signal, by delaying the above active driving signal. A control signal generator(330) provides a decoder control signal synchronized to the above active pulse signal, and is disabled by the activation of the active delay signal. And a row predecoder(340) generates a driving signal driving a specific word line of the memory bank ultimately, and receives the decoder control signal through a clock input stage.

Title: Fault Tolerant Management of Explicit Route on MPLS System
Inventor: JUN BYEONG CHEON
IPC: H04L12/28
Filed: 2002-05-24
Abstract: PURPOSE: An ER-LSP(Explicit Routed-Label Switched Path) management method for admitting the fault of an MPLS(Multi Protocol Label Switching) system and an apparatus therefor are provided to prevent that unnecessary control messages are generated by the resetting of all ER-LSPs by managing LDP(Label Distribution Protocol) session information and state information according to the ER-LSPs and resetting only a corresponding ER-LSP by stored information when an LDP session is connected after a system and link fault is removed. CONSTITUTION: An ER-LSP database(40) stores an ER-LSP ID, an ER-LSP state, link information, and a link state with respect to each ER-LSP. An ER-LSP setup/release management unit(20) manages the setup and release of the ER-LSP. A state informing block performs a line recovery and LDP session setup informing function and a link fault and LDP session release informing function. If the fault of the LDP session and link is sensed by the state informing block, an ER-LSP fault management unit(60) performs the fault management function of the ER-LSP, releases assigned resources, and releases internal switch connection setup. If the state of the ER-LSP is changed by the ER-LSP setup/release management unit(20) and the ER-LSP fault management unit(60), an ER-LSP state management unit(30) changes ER-LSP state information and LDP session information of the ER-LSP database(40). When the LDP session setup is sensed by the state informing block, an ER-LSP resetting task block(90) requests resetting with respect to the ER-LSP of the setup state and the ER-LSP of a down-state.
