A method is provided for programming a block of memory cells of a non-volatile memory device. A first group of memory cells of the block of memory cells is selected. At least one programming pulse is programmed into all memory cells of the first group. A threshold level is detected for each one of the memory cells of the first group only. The first group of memory cells is verified by comparing each one of the detected threshold levels with predefined target levels provided for each one of the first group of memory cells.

The memory array (2) has at least one memory area (5) that includes a plurality of conductive lines (3) and a plurality of memory cells (4) connected to the conductive lines (3). The conductive lines (3) are arranged at positions (n) within the memory area (5).

摘要:
A nonvolatile semiconductor memory device includes transistor-based memory cells. Each memory cell has a first and a second source/drain region, a channel region separating the first and the second source/drain region, a storage layer and a control gate. The control gates of the memory cells are connected to word lines. The first and second source/drain regions are connected to bit lines respectively. Each memory cell may be programmed by injecting first charge carriers of a first polarity and may be erased by injecting second charge carriers having the opposite polarity into the storage layer respectively. By applying a high stress voltage between bit line and word line, weak insulator structures may break through such that they become detectable as short-circuits by a low voltage leakage test. By applying the stress voltage contemporaneously on both sides of the memory cells, an early overerase/overprogram, resulting from hot carrier injection, is avoided.

摘要:
A memory device is provided including memory cells that are capable of switching between at least two states, where the threshold of a sense signal for detecting the current state depends on a data content of the memory cell. Parallel to a user data block, a primary control word including a predetermined number of bits of a first state is stored in a check section of the cell array. The check section is read by applying sense signals of different amplitudes, where in each case a secondary control word is obtained. By checking in each secondary control word the number of bits of the first state, the margins of the current sense signal amplitude towards the sense window limits may be checked and the sense signal amplitude may be adapted permanently to a sense window drift, so as to enhance the reliability of the memory device.
