摘要： The present disclosure includes apparatuses and methods related to memory cell state in a valley between adjacent data states. A number of methods can include determining whether a state of a memory cell is in a valley between adjacent distributions of states associated with respective data states. The method can also include transmitting a signal indicative of a data state of the memory cell and whether the state of the memory cell is in the valley.

摘要： An embodiment of a data read path includes recovery and decoder circuits. The recovery circuit is operable to recover coded data from a storage medium, and the decoder circuit is operable to detect, in the recovered data, a write error that occurred during a writing of the coded data to the storage medium. For example, such an embodiment may allow detection of a write error that occurred while writing data to a bit-patterned storage medium.

摘要： The present disclosure includes methods and apparatuses for mapping between program states and data patterns. One method includes: programming a group of G memory cells such that a combination of respective program states of the group maps to a constellation point corresponding to a received N unit data pattern, the group used to store N/G units of data per memory cell; wherein the constellation point is one of a number of constellation points of a constellation associated with mapping respective program state combinations of the group of memory cells to N unit data patterns; and wherein the constellation comprises a first mapping shell and a second mapping shell, the constellation points corresponding to the respective first and second mapping shells determined, at least partially, based on a polynomial expression of order equal to G.
