    • The disclosed invention is a nonvolatile memory having a memory field and a redundant field within a single semiconductor chip. The redundant field is used to store essential information regarding device formulation or address mapping. The nonvolatile memory includes a programming circuit capable of programming and verifying a selected memory cell within the redundant field with single-bit data while a selected memory cell within the memory field is being programmed and verified with multi-bit data. The nonvolatile memory also includes a reading circuit capable of reading single-bit data from a selected memory cell within the redundant field while multi-bit data is being read from a selected memory cell within the memory field. Therefore, according to this invention a single-bit operation for the redundant field can be performed without disturbing a multi-bit operation for the memory field.

    • Integrated circuit memory devices contain a plurality of nonvolatile memory cells and preferred circuits for selectively configuring the memory cells as multi-bit memory cells having more than two programmable states, during a multi-bit mode of operation, or for configuring the memory cells as single-bit memory cells during a single-bit mode of operation. The preferred circuits contain first and second sense amplifiers that can be electrically coupled to first and second strings of memory cells in the plurality thereof, and a pass transistor for electrically connecting sense nodes of the first and second sense amplifiers together during the multi-bit mode of operation. The first and second sense amplifiers also contain first and second latches, respectively, and the first and second latches each have normal and complementary outputs. The normal outputs of the first and second latches are electrically coupled to first and second input/output lines, respectively. First and second latch control circuits are also provided for enabling the single-bit and multi-bit modes of operation. Here, the single-bit mode of operation (i.e., two-state mode of operation) may be used for high fidelity applications requiring fault-free operation and the multi-bit mode of operation (e.g. four-state mode of operation) may be used for applications involving the storage of mass amounts of information such as audio data, where memory loss or corruption of small amounts of data does not significantly affect the fidelity of the information when read as a whole.
