Abstract:
A memory device having the function of detecting locking or unlocking condition of a remote controller, comprising:a battery;a key circuit including a lock key and an unlock key, one end of the lock key and the unlock key being connected with a positive terminal of the battery;an encoding unit connected with a second end of the lock key and the unlock key of the key circuit, the output end of said encoding unit being connected with an emitting driving circuit, whereby when one key of the key circuit is actuated, the encoding unit will generate a code and output the code through said emitting driving circuit;a memory unit having an input end which is connected with said second end of the lock key and the unlock key of the key circuit, and a power source thereof connected with the positive terminal of the battery;a light emitting element having one end connected to an output end of the memory unit; anda testing key having one end connected to a second end of the light emitting element, and a second end thereof being grounded, whereby when the testing key is actuated, (1) if the output of the memory unit is in high voltage, then the light emitting element will light; and (2) if the output of the memory unit is in low voltage, then the light emitting element will not light.
