    摘要: In accordance with embodiments of the invention, there are provided integrated circuits, memory controller, a method for determining a level for programming or erasing a memory segment, and a method for determining a wear level score for a memory segment. In an embodiment of the invention, a method for determining a level for programming or erasing a memory segment is provided, wherein a first level for programming or erasing a memory segment is determined as a function of an initial program/erase level. Furthermore, a first updated level is determined for a subsequent program/erase operation of the memory segment and a second level for programming or erasing the memory segment subsequent to programming or erasing the memory segment is determined using the first level, wherein the second level is determined as a function of the first updated level.

    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.
