CONSTITUTION: Whether a message, received in a signaling connection control part(SCCP) inside a No.7 message handling device, is a management message for a state change from a destination or a time out message of a timer for each sub system of the destination is confirmed. If the message is the management message for the state change from the destination, data inside the SCCP are updated to the management message, and whether the timer for the sub system of the destination driven is confirmed. If the timer is not being driven, whether the management message is a sub system prohibited(SSP) message is decided. If the management message is the SSP message, the unavailability of the sub system of the destination is broadcasted to each local sub system and a signaling message handling processor(SMHP), and the timer is driven. If the timer is being driven, the timer is driven after being released. If the message is the time out message of the timer for each sub system of the destination, data in a last SCCP is broadcasted to the local sub system and the SMPH.

Abstract: PURPOSE: A method for fabricating an ultra high integrated memory device is provided to prevent oxidation and lifting of a metal electrode, to prevent damage of a substrate in a contact etch process, and to improve step coverage of a metal line by a better profile of a contact hole. CONSTITUTION: A silicon substrate(401) is provided with the first dielectric layer(402). Then, a barrier metal(403), a tungsten layer(404) for bit lines, and a mask nitride layer(405) are patterned on the first dielectric layer(402), and nitride spacers(406) are formed on edges of the pattern. Next, the second dielectric layer(407) and a silicon-rich insulating layer(408) are formed on the resultant structure, and then another dielectric layer is formed on the silicon-rich insulating layer(408). Particularly, the silicon-rich insulating layer(408) acts as a polishing stopper in the subsequent polishing step. Thus, though the polishing is performed faster at peripheral portions of a wafer, the second dielectric layer(407) is protected by the silicon-rich layer(408) while the polishing is done at central portions of the wafer. Accordingly, the second dielectric layer(407) has a thickness enough to prevent penetration of oxygen in the formation of a capacitor(410).

Abstract: PURPOSE: A terminal having a detachable memory is provided to manufacture a non-volatile memory in a detachable system to re-use user information data, so that users do not have to re-input stored telephone numbers in a fault or change of a terminal. And the terminal is manufactured with an ESD(Electro Static Discharge) prevention-processed package, to prevent natural losses of stored information. CONSTITUTION: A detachable memory(32) is inserted in an interface unit(31) of a terminal, and the terminal is turned on. In a standby mode of the terminal, a CPU on a PCB(Printed Circuit Board) inside the terminal initializes a flash memory. The CPU loads user information, such as authentication parameters, MIN(Mobile Identification Number)s, ESN(Electronic Serial Number)s and base station information, to an SRAM, and normal operations are performed. When substituting a new terminal for the terminal due to faults or variable reasons, only the non-volatile detachable memory(32) can be separated for connection with the new terminal. Charges are settled by non-volatile user information stored in the detachable memory(32), therefore the detachable memory(32) can be used in a terminal of another user.
