Abstract
A memory card includes data protection circuitry preventing unauthorized reading of data from and writing of data into a memory. Authorized memory access begins when specific data is attempted to be written into a specific address. This step activates a timer for an active time period during which data can be read from or written to the memory card upon receipt of appropriate control signals. When the active period of the timer has elapsed, access to the memory card is denied until the specific data is again attempted to be written into the specific address.
