Abstract
Various systems and methods for generating error indications are disclosed herein. In some cases, the error indication is used as an erasure pointer in a memory access system. As one particular example, a system for generating an erasure pointer is disclosed that includes accumulating a number of error values into an overall error value, and comparing the overall error value to an error threshold. When the overall error value exceeds the error threshold, an erasure pointer is generated. In one particular case, the error values are derived from a look up table using thermometer codes generated by an analog to digital converter. In other cases, the error values are derived from comparing a soft output with a reliability threshold.
