摘要： Described embodiments provide enhanced read accuracy of a multi-level cell (MLC) flash memory. A read request for desired cells is received by a media controller of the memory. The media controller sets m thresholds to initial values, each threshold corresponding to a cell voltage level of the memory, and measures the cell voltage level of a given cell. For each of the desired cells of the memory, the media controller iteratively, until the measured cell voltage level converges on one of the thresholds, compares the measured cell voltage level to the thresholds. If the measured cell voltage level does not converge on one of the thresholds, the media controller updates the thresholds, remeasures the cell voltage level and compares the remeasured cell voltage level to the updated thresholds. Once the measured cell voltage level converges on a threshold, the media controller determines a binary level of the cell.
摘要翻译：所描述的实施例提供了多级单元（MLC）闪速存储器的增强的读取精度。存储器的介质控制器接收对期望单元的读取请求。介质控制器将m个阈值设置为初始值，每个阈值对应于存储器的单元电压电平，并且测量给定单元的单元电压电平。对于存储器的每个期望的单元，媒体控制器迭代地，直到所测量的单元电压电平收敛于其中一个阈值，将测量的单元电压电平与阈值进行比较。如果测量的单元电压电平没有收敛于其中一个阈值，则介质控制器更新阈值，重新测量单元电压电平，并将重新测量的单元电压电平与更新的阈值进行比较。一旦所测量的电池电压电平收敛于阈值，则介质控制器确定电池的二进制电平。

摘要： Described embodiments provide a method of cancelling inter-track interference (ITI) from one or more sectors read from a desired track of a storage medium. A read channel reads sectors in a desired track of the storage medium. A decoder of the read channel decodes the read sectors, and if the read sectors are incorrectly recovered from the storage medium, selected sectors of a first adjacent track and a second adjacent track are read. An ITI canceller of the read channel estimates ITI in the read sectors of the desired track corresponding to the selected sectors of each adjacent track and subtracts the estimated ITI of each adjacent track from the data for the sectors of the desired track, providing updated sector data. The ITI cancelled data is replayed to the decoder, which decodes the ITT cancelled data and provides the decoded ITI cancelled data as output of the read channel.
