摘要
In a non-volatile memory device, the parameters used in write and erase operation are varied based upon device age. For example, in a programming operation using a staircase waveform, the amplitude of the initial pulse can be adjusted based upon the number of erase-program cycles (hot count) of the block containing the selected physical page for the write. This arrangement can preserve performance for relatively fresh devices, while extending life as a devices ages by using gentler waveforms as the device ages.
