摘要： Each memory cell of a plurality of memory cells of a memory has a well, source and drain regions, a storage layer, and a gate. The memory cells are in a matrix. Same column drain regions connect to the same bit line, same row gates connect to the same word line, and same column source regions connect to the same source line. The memory is programmed by applying a first voltage to a word line electrically connected to a memory cell of the plurality of memory cells, applying a second voltage different from the first voltage by at least a programming threshold to a bit line electrically connected to the memory cell, applying a third voltage different from the first voltage by at least the programming threshold to a source line electrically connected to the memory cell, and applying a substrate voltage to the plurality of memory cells.

摘要： Multi-stage pulses are used to program/erase the memory so as to reduce the slow program/erase bit issue. A first predetermined voltage bias is applied to a memory cell for a predetermined number of times. Each time the voltage bias is applied to the memory cell the memory is verified against a criterion. If the verification failed after the predetermined number of times applying the first predetermined voltage bias, a second predetermined voltage bias is applied to program/erase the nonvolatile memory. If the verification failed after applying the second predetermined voltage bias, a third predetermined voltage bias is applied to program/erase the nonvolatile memory.

摘要： A nonvolatile memory device for reducing programming current and improving reliability comprises a memory cell array, a write circuit, and a verification circuit. The memory cell array comprises memory cells arranged at crossing points of a bit-line and word-line matrix of the memory cell array. The write circuit provides multiple variable pulses to each word-line for programming. The multiple variable pulses have predetermined amplitude for keeping gate injection current roughly maximum while lowering conduction current during programming operation. The verification circuit senses variation of the conduction current during the programming operation, and disables the programming operation if the sensed conduction current during the programming operation reaches a predetermined value.

摘要： A method for programming/erasing a nonvolatile memory uses the multi-stage pulses to program/erase the memory so as to reduce the slow program/erase bit issue. The method applies a first predetermined voltage bias to a memory cell for a predetermined number of times. Each time the voltage bias is applied to the memory cell the memory is verified against a criterion. If the verification failed after the predetermined number of times applying the first predetermined voltage bias, a second predetermined voltage bias is applied to program/erase the nonvolatile memory. If the verification failed after applying the second predetermined voltage bias, a third predetermined voltage bias is applied to program/erase the nonvolatile memory.
