Error bit found in memory system

摘要

A method, system, and device are described for finding error bits in a memory system. For example, a controller or memory controller can read code words from a memory medium. The code word may include a set of bits each corresponding to each MSR (Minimum Substitution Region) of the memory medium. Each MSR may contain a portion of a memory cell of a memory medium and may be associated with a counter to count the number of error bits in each MSR. When the controller uses an error control operation to identify the quantity of error bits in the code word, the controller updates the value of the counter associated with each MSR corresponding to the quantity of error bits to count the error bit count for each MSR. can do. In some cases, the controller may perform the operations described herein as part of the background operation.
