    摘要: One embodiment of the technology is an apparatus, a memory integrated circuit. The memory integrated circuit has word line address decoding circuitry. The circuit allows selection of a single word line to have an erase voltage. A decoder circuit includes an inverter and logic. The inverter has an input, and an output controlling a word line to perform the erase operation. A voltage range of the input extends between a first voltage reference and a second voltage reference. Examples of voltages references are a voltage supply and a ground. In some embodiments, this wide voltage range results from the input being free of a threshold voltage drop from preceding circuitry limiting the voltage range of the input. The logic of the decoder is circuit is controlled by a word line address to determine a value of the input of the inverter during the erase operation.

    摘要: Various aspects of a nonvolatile memory have an improved erase suspend procedure. A bias arrangement is applied to word lines of an erase sector undergoing an erase procedure interrupted by an erase suspend procedure. As a result, another operation performed during erase suspend, such as a read operation or program operation, has more accurate results due to decreased leakage current from any over-erased nonvolatile memory cells of the erase sector.

    摘要: A nonvolatile memory array is divided into multiple memory groups. The nonvolatile memory array receives an erase command to erase a first set of the memory groups, and not a second set of the memory groups. The control circuitry is responsive to the erase command to erase the first set of memory groups, by applying a recovery bias arrangement that adjusts threshold voltages of memory cells in at least one memory group of the second set of memory groups. By applying the recovery bias arrangement to memory cells in at least one memory group of the second set of memory groups, erase disturb is corrected during the recovery bias arrangement, at least in part.
