Abstract: A sensing circuit. In one embodiment, the sensing circuit includes a memory circuit including a first bitline that sinks a first leakage current, a compensation device coupled to the memory circuit, and a compensation circuit coupled to the compensation device. The compensation circuit includes a second bitline that sinks a second leakage current that matches the first leakage current. The compensation device is operative to compensate the first leakage current through a current based on the second leakage current. According to the system and method disclosed herein, the compensation device and compensation circuit prevents errors when determining the state of the memory cell.

Abstract: A redundant memory array has r columns of redundant memory cells, r redundant senses, and a redundant column decoder. Redundant address registers store addresses of defective regular memory cells. Redundant latches are provided in n groups of r latches. Redundancy comparison logic compares addresses of defective regular memory cells with an external input address. If the comparison is true, what is provided is: a DISABLE_LOAD signal to disable the regular senses for one of the n groups of m columns, an ENABLE_LATCH signal to one of the n groups of m columns to disables corresponding regular senses, and one or r REDO signals to a respective one of the r redundant latches in one of the n groups that is disabled. The selected one of the redundant latches activates one of the r redundant senses to access a redundant column.

Abstract: An apparatus and method for providing a temperature compensated reference current in an electronic device is disclosed. The temperature compensated reference current is compensated for temperature and other circuit variations. The reference current is provided by an improved reference current generator and may be used in a memory device or any other desired circuit.

Abstract: An output buffer includes an output stage formed by a pull-up transistor and a pull-down transistor connected in series between a supply line set at a supply potential and a ground line set at a ground potential. The output buffer further includes a pre-biasing stage for pre-biasing the control terminal of the pull-up transistor and a pre-biasing stage for pre-biasing the control terminal of the pull-down transistor in order to bring these transistors to the turning-on threshold.
