Non-volatile memory with precise programming
Memory cells are programmed to threshold voltage distributions that correspond to data states by applying a series of voltage pulses to a selected word line connected to a set of non-volatile memory cells selected for programming. Tighter threshold voltage distributions will result in fewer errors when reading the data at a later time. To create tighter threshold voltage distributions during programming, the system slows down the programming of memory cells as the memory cells approach their target threshold voltage by reducing the effective pulse width of the voltage pulses. The voltage pulses are divided into portions, with each portion corresponding to a subset of the pulse width or a subset of the time period that the voltage pulse is applied. Memory cells that are approaching their target threshold voltage will be slowed down by inhibiting those memory cells from programming during later-in-time portions of the voltage pulses. |

Magnetic disk device and method
According to an embodiment, a magnetic disk is provided with a servo sector in which a preamble and a burst pattern are recorded. A recording frequency of the preamble is different from an even multiple of a recording frequency of the burst pattern. A controller determines a demodulation period of the burst pattern while a magnetic head passes through the servo sector. The controller acquires a first phase of a demodulation signal of the burst pattern and acquires first position information of the magnetic head, by demodulating the burst pattern in the demodulation period. The controller corrects the first position information on the basis of the first phase. The controller executes positioning control of the magnetic head on the basis of second position information that is post-correction first position information. |
