Title: Overdriving method for sense amp
Inventor: JUNG HEON SAM
IPC: G11C11/40
Filed: 2000-02-15
Abstract: PURPOSE: An over driving method of a sense amplifier is provided to be developed to a VDL level with a faster speed, by applying two signals(SAP1,SAP2) simultaneously in an interval during a time(tov) of applying an overdrive control signal. CONSTITUTION: A bit line is developed to a power supply voltage(VDDCLP) level by applying a control signal(SAP1) during a control signal applying time(tov). Then, the bit line is developed to a power supply voltage(VDL) level by applying another control signal(SAP2) during a fixed interval(tov1) of the above time(tov). The control signal applying times(tov,tov1) are determined by a simulation. Because two voltages(VDDCLP,VDL) are used in a sense amplifier during the above intervals, the voltage levels are decreased. When the bit line approaches to the voltage level(VDL), the decrease of the two voltages are reduced and thus the two voltages approach to the original voltage level.

Abstract: PURPOSE: A data service method for a communication system is provided to prevent a duplex division process and decrease a system load by requesting a data call using a specific service option defined between mobile terminals and directly switching a voice traffic path to a terminating mobile terminal without an inter-working function(IWF) for setting a traffic path. CONSTITUTION: The first mobile terminal requests a data call to the second mobile terminal(S500). An MSC(Mobile Switching Center) checks whether the call requested from the first mobile terminal is a specific service option(S501). If the requested call is the specific service option, a call setting is not transmitted to an IWF and the requested call is processed by a general voice call processing method although the requested call is a call for requesting a data service(S502). If the first mobile terminal is a traffic state, a VCE(Voice Channel Equipment) sets an RLP(Radio Link Protocol) with the first mobile terminal(S503). The MSC requests a paging to the second mobile terminal(S504). When the first mobile terminal responds to the paging, the MSC does not the call setting to the IWF and processes the requested call by the general voice call processing method although the call is a call for requesting the data service when the second mobile terminal responds as the specific service option(S505). If the second mobile terminal is the traffic state, the VCE sets the RLP with the second mobile terminal(S506). The MSC switches the data traffic path to the first mobile terminal when the second mobile terminal responds and sets the data call(S507). The first mobile terminal sets a point-to-point protocol(PPP) to the second terminal through the set data path(S508), and transmits and receives data between the first mobile terminal and the second mobile terminal when the setting of the PPP is completed(S509).
