Abstract
A data storage apparatus includes an integrated circuit further including a control unit and a memory array of charge-based memory cells. The memory array includes a first subsection which is operable as a memory, and includes a second subsection which is operable as a dosimeter. The control unit is operable to provide a reference current and to conduct memory access operations to access the memory with reference to the reference current. The control unit is further operable to analyze a statistical distribution of read currents by using memory access operations in the second subsection. Said analysis involves counting of logical read errors of the memory access operations and calibrating the reference current depending on a number of counted logical read errors being indicative also of a Total Ionizing Dose, TID.
