Abstract
A security system having at least one electronic lock and one electronic key. The electronic lock has a memory device which can maintain the data while there is no current supplied to the memory device, and alter the data only when current is supplied, thus providing a non-continuous current drain system. The electronic lock further reduces the chance of error due to high velocity particles which can otherwise alter data in a memory device. The electronic lock applies current to the memory only when a key has been inserted in the lock, and terminates the current to the memory when the key has been removed or the function requested by the key is invalid or the function requested is completed. Alternatively, the electronic lock may apply the current to the memory only if data is to be output from or input to the memory.
