1. A device comprising:
- a comparator configured to select a first threshold in response to a value of a variable node indicating a first logical value and to select a second threshold in response to the value of the variable node indicating a second logical value; and
a variable node update circuit configured to adjust the value of the variable node in response to a number of unsatisfied check nodes associated with the variable node satisfying the selected threshold.

Abstract
A device includes a comparator configured to select a first threshold in response to a value of a variable node indicating a first logical value and to select a second threshold in response to the value of the variable node indicating a second logical value. The device also includes a variable node update circuit configured to adjust the value of the variable node in response to a number of unsatisfied check nodes associated with the variable node satisfying the selected threshold.
