摘要:
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.
摘要:
An integrated circuit and a method for transferring data is provided. One embodiment provides a method for transferring data in an integrated circuit. The method includes driving a first line in accordance with data to be transferred. The data is transmitted from the first line to a second line based on a capacitive coupling.
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.
