Abstract
An input apparatus is provided. The input apparatus includes a plurality of keys, a micro-control unit, a coordinate output circuit, and a key control circuit. The micro-control unit includes a lock-status controlling module, a password comparing module, and a unlocking module. The lock-status controlling module is for receiving input signals from the keys when a memory of the input apparatus is in a locked status, and transmits the input signals to the password comparing module. The password comparing module is for comparing the input signals with a predetermined password, and generating a unlocking signal to the unlocking module when the input signals are the same as the predetermined password, thereby obtaining valid operations on the memory. Therefore, utilizing the input apparatus and password control method, it is feasible to prevent others from validly accessing the memory, and thus to protect the data stored in the memory.
