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.
