Abstract
A memory device incorporates a chip enable protection circuit implementing a secured chip enable method providing a passcode protected enable scheme with secure chip disable for the memory device. The passcode can be programmed at manufacturing or programmed by the user. Memory device access is enabled by receiving the correct passcode and memory device access is denied when the wrong passcode is entered. Furthermore, the secured chip enable method implements secure chip disable where the memory device is disabled in response to receiving wrong passcodes repeatedly for a maximum number of tries.
