Method and system for reducing the effect of component aging

摘要

Methods, systems and circuits for reducing aging of at least one component of a data path are disclosed. First data transmitted over a data path may be monitored in an active state to allow generation of second data, where the second data may be transmitted in an inactive state over the data path to improve the balance of any imbalance in the static probability of one logical state versus another caused by transmission of the first data. Portions of data to be transmitted over a data path may be compared to previously-transmitted portions of data to determine a respective data bus inversion (DBI) setting each portion of data, where the DBI settings may be used to increase the toggling of bits of the data path and improve the balance of the static probability of one logical state versus another.

1. A method of reducing aging of at least one component of a data path, said method comprising:
monitoring a first data signal to determine a quantity associated with a relative number of instances of a first logical state and a second logical state, wherein said first data signal is communicated to a device over said data path, and wherein said first data signal represents a greater number of instances of said first logical state than said second logical state; determining that said data path is inactive; and while said data path is inactive, communicating a second data signal over said data path to reduce aging of at least one component of said data path, wherein said second data signal represents a number of instances of said second logical state that exceeds a number of instances of said first logical state by said quantity.
