20120079353 | Memory Quality Monitor Based Compensation Method and Apparatus - In one embodiment, an encoder reads a set of data from memory cells to obtain retrieved data influenced by one or more distortion mechanisms as a result of having been stored. A quality metric is generated responsive to the retrieved data that changes in value responsive to differences between the user data and the associated retrieved data. A quality monitor establishes a relationship between a current value of the quality metric and a threshold value and monitors the relationship as being indicative of a degradation of the quality of the retrieved data, and selectively initiates an error response. In another embodiment, a correction value is iterated through a set of values as a quality metric is monitored such that the value of the quality metric which most closely approaches the value of the quality metric immediately subsequent to an initial writing of the data can be selected. | 03-29-2012 |
20120194221 | ADVANCED CONVERTERS FOR MEMORY CELL SENSING AND METHODS - A counter configuration operates in cooperation with a delay configuration such that the counter configuration counts an input interval based on a given clock speed and a given clock interval while the delay configuration provides an enhanced data output that is greater than what would otherwise be provided by the given clock speed. The counter configuration counts responsive to a selected edge in the clock interval. An apparatus in the form of a correction arrangement and an associated method are configured to monitor at least the delay configuration output for detecting a particular time relationship between an endpoint of the input interval and a nearest occurrence of the selected clock edge in the given clock signal that is indicative of at least a potential error in the enhanced data output and determining if the potential error is an actual error for subsequent use in correcting the enhanced data output. | 08-02-2012 |
