Claim:
1. A system for improving radiation tolerance comprising: a control section comprising a non-transitory storage medium including machine-readable instructions comprising; a first plurality of machine-readable instructions that operates the control section to write to a floating gate transistor a plurality of times, wherein each write operation comprises applying a bias in a semiconductor substrate region of said floating gate transistor that induces a tunneling effect that causes an amount of charge to gather on a floating gate region of said floating gate transistor; a second plurality of machine-readable instructions are designed or constructed to operate the control section to control a radiation source to irradiate said floating gate transistor at a predetermined radiation threshold; and a third plurality of machine-readable instructions are designed or constructed to operate the control section to determine if data on said floating gate transistor is above or below a predetermined data corruption threshold; wherein said first plurality of machine-readable instructions are designed or constructed to operate the control section to remove charge from said floating gate transistor and write to said floating gate transistor an increased number of said plurality of times until said data is maintained above said predetermined data corruption threshold.
