Abstract
An integrated circuit device includes a first memory cell that stores data representative of configuration data when operating in a first mode, wherein the first memory cell stores data representative of user-accessible data when operating in a second mode. The integrated circuit device also includes a second memory cell that stores a value indicating whether the first memory cell is operating in the first mode or is operating in the second mode. The integrated circuit device further includes a switch coupled to the first memory cell and controlled by the second memory cell, wherein the switch provides a defined value to be read in place of the stored data of the first memory cell when the second memory cell stores the value indicating that the first memory cell is operating in the second mode.
