20080279026 | Signal sensing circuit and semiconductor memory device using the same - A signal sensing circuit and a semiconductor memory device using the same are provided. The signal sensing circuit comprises a sense amplifier, a kick transistor, a first control transistor, a second control transistor, a pre-charge circuit, and a recovery circuit. The kick transistor is used to pull up the operation voltage of the sense amplifier to improve the small signal sensing speed of the sense amplifier. After the signal is sensed, the recovery circuit will pull down the operation voltage of the sense amplifier to the standard level. In the present invention, the small signal sensing speed is greatly improved and the operation voltage of sense amplifier is kept away from the saturated level. | 11-13-2008 |
20090129182 | Memory module with failed memory cell repair function and method thereof - A memory module with failed memory cell repair function and method thereof are provided. The memory module comprises a programming interface, a mode register, a control signal generator, a fuse unit, a main memory array and a redundant memory array, wherein the programming interface is defined by selecting pins from a standard interface of the memory module. The programming interface is used to input a plurality of programming commands and a plurality of programming data. When the failed memory cells have occurred within the main memory array, the mode register will enter into a programming mode according to the programming commands, and the control signal generator will program the fuse unit, such that the redundant memory cells of the redundant memory array will be used to replace the failed memory cells. Thus, the fuse unit can be programmed directly through the standard interface, and the repairing period and the cost will be reduced efficiently. | 05-21-2009 |
