    摘要： In a non-volatile memory circuit, techniques are presented so that bad columns can be ignored and/or replaced during memory data input and output operations. A column redundant circuit for this purpose reduces circuit size and improves performance. User data is grouped in an interleaved manner so that data belonging to consecutive logical address will be distributed into different physical locations. For example, all column data can be physically grouped into, say, 5 divisions and user data can be written into or accessed from one division after another consecutively. Each division has its own clock control. The column redundancy block can generate bad column locations' information and send it to control logic to switch the user clock to a different division clock, thereby skipping bad columns. By controlling the clocks for different columns, the user can directly access good columns without touching bad columns.

    摘要： The present invention discloses a method of fabricating dual trench isolated epitaxial diode array. This method starts with the formation of heavily-doped first conductivity type regions and heavily-doped second conductivity type regions on the substrate, followed by epitaxial growth, then the formation of the isolations between diode array word lines by deep trench etch and the formation of the isolations between bit lines vertical to deep trenches by shallow trench etch, and finally the formation of separate diode array cells in the regions enclosed by deep and shallow trench isolations by ion implantation. This invention also provides a method of preventing the crosstalk current between adjacent word lines and bit lines of epitaxial diode arrays isolated by foregoing dual shallow trenches. This invention can be used for diode-driven, high-density, large-capacity memory, such as phase change random access memory, resistive memory, magnetic memory and ferroelectric memory; the method thereof is completely compatible with conventional complementary metal-oxide semiconductor (CMOS) process, and because the diode arrays can be formed before the formation of peripheral circuits, no drift of peripheral circuits will be caused by the thermal process thereof, thereby solving the technical challenge of fabricating high-density, large-capacity embedded phase change random access memory.

    摘要： System and method for resource admission and control is disclosed. The system for resource admission and control includes an interface unit for application function unit configured to receive service request sent from the application function unit; a policy decision function unit configured to identify the type of an access network according to the service request received by the interface unit for the application function unit and select corresponding service logic for resource admission and control according to the identified type of access network. According to the technical solutions, no matter the request for resource is made to a fixed access network defined in TISPAN, or to a wireless access network defined in the 3GPP, the policy decision function unit xPDF may identify the type of the access network and select corresponding service logic to perform resource admission and control. The xPDF conceals the details of the access network from the AF such that the solution for network construction can be simplified and the system maintenance may become simple and convenient.

    摘要： A connector includes an insulating housing having a rear wall of which a front side extends forward to form a tongue portion and a back side defines a concave groove in accordance with the tongue portion. The tongue portion defines a plurality of terminal grooves. A plurality of terminals each has a fixing portion fixed in a rear of the terminal groove with a rear end thereof further projecting into the concave groove, a contact portion disposed in the terminal groove, and a soldering tail stretching outside the insulating housing. A water-proof member is formed in the concave groove by injecting molten water-proof colloid in the concave groove to seal up intervals between the fixing portions of the terminals and inner sides of the rears of the terminal grooves. A metal shell is molded in the insulating housing.
