Device for the protection of stored data using a time delay circuit

摘要

Disclosed is a device for protection of stored data comprising protection means to control a signal to enable the programming of a memory, the programming being permitted when the enabling signal is in a first state and prohibited when the enabling signal is in a second state, the protection means including a supply voltage drop detection device to set the enabling signal in the second state when the supply voltage is below a threshold, said device further comprising a time delay circuit capable of setting the enabling signal in the second state during a given period when a control signal goes into a first state.
